How do you calculate the sq ft of a 6.6 foot circle rug?
First you determine the radius of the circle. If 6.6 feet refers to the diameter, divide that by 2 to get the radius. Then you use the standard formula for the area of a circle.
What is the area of a circle with a diameter of 56 millimeters?
Using 3.14 as Pi the area of circle is: 2461.76
How do you divide a circle into equal pieces?
It depends on the number of pieces that you need. To Divide the Circle in Half: There are two easy ways to divide a circle: using a compass or using six more circles of the exact same size. Using Six More Identical Circles 1. Place the six identical circles around original, so that they all touch it. Every one of these circles should touch the center circle, and it's two neighbours. The fit should be perfect. 2. Mark the points where each of the surrounding circles touch the center circle. 3. Draw a line between any two opposing marks. This line exactly divides your circle. Using a Compass 1. Set the width of the compass to equal the radius of the circle. This can be done by trial and error if necessary. That is, choosing a likely size, draw a circle, compare with original, and adjust. 2. Mark a point on the edge of the original circle. 3. Place the point of the compass on this spot. 4. There are two new points on the circle which the compass, on either side of the first point. Mark the new points. 5. For each new point, place the point of the compass there and mark one more point, as before. You should now have 5 points marked. 6. If you wish, mark a sixth point from the two newest marks. Both marks should touch the same point, if they don't your radius or your marks have been inaccurate. 7. Draw a line between any two opposing marks. This line exactly divides your circle. To Divide the Circle in Sixths This is the same as dividing the circle in half, above, but draw lines between all three sets of opposing marks. To Divide the Circle in Thirds 1. Initially divide the circle into sixths. 2. These three lines should meet at the center of the circle. Mark the center. 3. Remove every other line segment between the center and the edge of the circle (circumference). To Divide the Circle into N Equal Parts You will need a protractor for this, and possibly a calculator. 1. Initially divide the circle into sixths, above. 2. Mark the point where the divisions cross, this is the center of the circle. 3. Remove five of the six line segments between the center and edge (circumference) of the circle. 4. Determine angle of each wedge by dividing 360 by N ( 360/N ) where N is the number of equal pieces that you want. For example if you want 9 pieces then 360/9 = 40. So you wedge angle is 40 degrees. 5. With the center of the protractor at the center of the circle and the one line at 0 degrees, mark of your wedge angle on both sides of the line. For example, if your first line is straight up and down, then mark 40 degrees to the left and to the right. 6. Draw a line from the center of the circle, through your mark, and to the edge of the circle. 7. Continue marking of your angle around the circle and drawing lines, going both directions, until your marks meet. Further Information There are ways to divide circles using templates that are purchased. You may also make many more divisions using only a compass and strait edge, besides two and six, but these can be much more complex and are probably too difficult to describe without a diagram.
What do i do Multiply or divide first?
First comes multiply then comes divide.
When you divide fractions does the big number go first?
The number on the bottom of the fraction bar is first, then divide that by the top number :)
What are important assyrian inventions?
They were the first to divide the circle in to 360 degrees and used metal instead of bronze. Also, they were the first to establish the Library.
How did the Babylonians contribute to writing math and the study of astronomy?
They were the first people to use numbers to describe physical phenomena, and they were the first to divide a circle into 360 equal degrees.
How many cm are there in a semi circle?
First the circle diameter must be given. for example, for a semi circle of diameter 8 centimeters:Step 1: the circumference of the full circle (= pi x Diam). result is: 25.12 cmStep 2: Divide the circumference in half. This is the length of just the curved part of the semi-circle. result: 12.56 cmStep 3: Add the diameter to the result of step 2.Step 4: The result is 12.56 + 8 = 20.56 cm. This is the perimeter of the semi-circle!Note point: There are 360 degrees in a circle, so a quarter of a circle has 90 degrees no matter what size the circle is. Half a circle has 180 degrees.
Explain how earths tilted axis is responsible for seasons?
The Babylonians are credited with the first systematic astronomical observations. They used the concept of angles to describe the positions of objects in the sky and they were the first to divide a circle into 360 equal degrees.
What is the diameter of 360 degree circle?
I am so happy to be the first person to answer this question on here. The equation for the radius of a 360 degree circle is 360/2(Pi) and of course, once you get the radius all you have to do is double it to get the diameter. So if you take Pi: 3.14159265... and multiply it by two you get: 6.2831853... and then you take that number and divide it into 360 degrees and you get: 57.29577... degrees (The Radius) and then you multiply that by two to get the diameter which is: 114.59155915...degrees, roughly, of course. My resource: The Code by Carl Munck (which you can find on youtube).
How do you draw a rhombus using a compass?
first you draw a circle, divide it into 4
How do you calculate the diameter of a circle if you know the area?
First, divide your answer by 2 Next, divide that answer by 3.14 Then, multiply that answer by 2 there's your answer
How to draw a pie?
An easy way to draw a pie is by first drawing a circle. Next, use lines to divide the circle into slices.
How do you divide a 20 diameter circle into 9 equal segments?
Forget the diameter. Find the centre. Draw any radius. Next, add another radius at 360/9 = 40 degrees to the first. Keep adding radii as you go around the circle. When it is in 9 equal slices you will have returned to the first radius. Done.
How to divide the circumference of a circle equally?
First you calculate the circumference of the circle using the standard formula C=pi x D, Where C is the circumference, D is the Diameter of your circle (measured across the widest part of the circle) and pi is a known constant of 3.14 (discovered by the ancient Greeks or is that ancient Geeks?). So if your circle is 300 mm across (12 inches in old terms) then it is calculated as so: 3.14 x 300 = 942mm circumference. To work out the distance between the points you need to decide how many points are required around the circle (circumference). For this explanation I will use 8 points and we know a circle has 360 degrees as seen on a compass therefore divide 360 degrees by 8 points as so: 360 / 8 = 45 degrees. Now the final part to calculate the distance from the first point to the second of 8 points we divide the circumference of the circle 942 mm by 360 degrees to find out the distance of one degree, I hope you are starting to see where I am going with this, as so: 942 / 360 = 2.61666667 mm then you take the answer for 1 degree of the circumference and multiply it by 45 degrees (which is one eight of the circle, giving us the eight points) as so: 2.61666667 x 45 = 117.75mm (or 4.71 inches). Hey presto 'simples' you have the answer! By the way pi is actually 3.14159 and the first people to be aware of such a constant were the Egyptians followed by the Babylonians although their pi's were not as accurate!
What were the Assyrian innovations?
The assyrians have created many things from paved roads to medicine. They were the first to divide a circle into 360 degrees and they also developed the concept longitude and latitude. They have also created calendars and wheels in their state. But most of all, they were the first to believe in Jesus Christ other than the holy land.
