How do you find the radius of a circle with a circumference of 92ft?

radius = 92/(2*pi) = 14.642 feet to 3 decimal places


A sector of a circle has a central angle of 80 degree and a radius of 5 meters. Find the area of the sector.?

It is: 80/360 times 25pi = 17.453 square meters rounded to 3 decimal places


When a circle has a radius of 6 feet find the arc length of a central angle of 12 degrees?

It is 12/360 times 12*pi = 2/5*pi or about 1.257 feet rounded to 3 decimal places


What is the area of a circle with a radius of 4.4?

To find the area of a circle based on its radius, multiply its radius squared by pi. Don't forget to square the radius before multiplying by pi, based on rules of BODMAS where you find powers of numbers before you multiply them.In this instance, (4.4 x 4.4) = 19.36. Multiplying this by pi gives us, accurate to two decimal places, 60.82. Don't forget to include the appropriate measurement. If the original measurement of the radius of the circle was in centimetres, then the area should be expressed in square centimetres. If the original measurement of the radius was in inches, then the area should be expressed in square inches.


What is the curcumference of a circle with a 16 meter radius?

Well first you find on your calculator you need to find pi which looks something like this π. Now to find the curcumference of any circle the formula is pi multiplied by the diameter. The radius is 16 metres, and the diameter of any circle in life is two multiplied by the radius. So you do π times by 32 which equals 100.53(I rounded it off to the nearest 2 decimal places). or even easier 3.14 x radius 2 l l l PI times raduis 2 and now for area 2 times 3.14 times raduis

How do you find the number of decimal places in a product of decimal numbers?

To find the number of decimal places in a product of decimal numbers, add up the total number of decimal places in each of the factors. For example, if you have 2.5 multiplied by 4.75, there are two decimal places in 2.5 and two decimal places in 4.75, so the product will have a total of four decimal places.


How do you find radius of a cylinder if the volume is 2355 and the height is 10?

Area of base of cylinder 2355/10 = 235.5 square units Radius is the square root of (235.5/pi) = 8.658 units rounded to 3 decimal places


What is 1.45 multiplied by 0.64?

To find the answer, multiply 1.45 by 0.64 just at you would if there were no decimals. When you get the answer, count the number of decimal places (Count from the right). There are 4 decimal places. Place a decimal 4 places from the right in your answer. 1.45 X 0.64 is 0.9280.


How does the number of decimal places in the product compare to the number of decimal places in the factors?

When you multiply decimals, you just ignore the decimal until the end, then, to find the amount of decimal places in your answer, you add the amount of decimal places in both your factors


Find the area of a circle with a diameter of 5?

The formula for area of a circle isA=pi*r2where A=area, and r=radius of circlethe radius is half the diameter (D=2r), so A = pi*2.52= 19.63 (to 2 decimal places)

How many square inches are in a 16 inch diameter circle?

To do this, you first find the radius of the circle. To do this, you divide 16 by pi, which gives 5.09 (to two decimal places). Half of this gives you the radius - around 2.55. You then square the radius, in this case giving approximately 6.48, and multiply it by two, which yields the answer of roughly 12.97. There's your answer - 12.97 inches squared (to two decimal places). N.B. These averages may seem slightly off, but I did the calculations on a calculator, simplifying each step.
