How do you divide a circle into 10 equal pieces without a compass?
Use a protractor and divide it into 36 degree wedges.
How do you draw a rhombus using a compass?
first you draw a circle, divide it into 4
How do you draw an angle 110 degree using ruler and compass?
Construct a circle and divide the circumference into 36 equal arcs Each arc will represent 10 degrees and 11 of them subtended to the circle's centre will create an obtuse angle of 110 degrees
How do you find the area of a circle without the radius?
if you have the diameter or the arc, then you can divide the diameter by two, or you can use the arc to calculate it.
Can you cut a circle into 5 equal parts?
AnswerThere are 2pi radians in a full circle. If we cut a circle into 5 equal parts, each central angle will have 2pi/5 (or 72 degrees), and each arc intercepted form those central angles will be (2/5)(pi)(r). AnswerYes, you can, using just a compass and straight edge. For any given circle you construct, construct a pentagon inside it using that compass and straight edge, then use the vertices of the pentagon to divide the circle into 5 equal sectors. Use the link below to see how the construction proceeds.
How do you divide a circle into 10 equal pieces without a compass?
Use a protractor and divide it into 36 degree wedges.
How do you divide a circle in to 6th equal parts?
If you have a protractor: Draw a line from the center of the circle to the outside (radius), then measure 60 degrees and draw another line. If you have a compass: Draw a circle using the compass, then, using your compass, place the compass needle on the edge of the circle, draw another circle (KEEP THE RADIUS THE SAME). Your two circles should have two intersection points. Place the needle on one of the intersection points and repeat the process. I suggest you look at:
How do you draw a rhombus using a compass?

How do you shade 2 thirds of a circle?
Using a protractor divide it into three parts, each of 120 degrees. Shade two of them
How do you divide a circle into thirds?
Assuming you know the location of the center of the circle, to divide a circle into thirds, do the following:mark a point on the circumference and, using a protractor, mark 120 degreesthen repeat for the final markA line from the mark on the circumference to the center will show an angle of 120 degrees.
How do you trisect an acute angle?
Use a protractor to measure the angle. Divide that number by 3 and that is the required angle. In general, an angle cannot be trisected using a compass and straight edge.
How do you divide a circle into five equal parts?
If a circle is comprised of 360 degrees, then each of the five sections will encompass 72 degrees. From an arbitrary radius, using a protractor, measure 72 degrees, then continue around the circle.
How do you draw a sphere?
step 1: make a circle with a compass step 2: divide the circle into 4 equal parts step 3: draw curved lines
How do you divide a circle into 14 pieces?
Divide 360 by 14, then draw two radii in the circle with this number of degrees between them. Then use a compass to mark off 14 equal arcs around the perimeter. Join the points to the centre.
How do you discover pi?
First draw a circle using a compass. Now, use a piece of string to help measure the circumference of the circle. Now measure the diameter of the circle. To discover Pi divide the circumference by the diameter.
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.
How can you use a compass to draw a circle if you know its raduis or diameter?
If you know the radius place the compass point on a ruler and the pencil end the radius distance away from it. Then put the point on the paper and spin to draw the circle. If you know the diameter divide by two to get the radius and place the compass point on a ruler and the pencil end the radius distance away from it. Then put the point on the paper and spin to draw the circle.
