62.8
The square root of 100 is 10.
The circumference of a circle is 2(pi)r = 2 x 3.14 x 10 =6.28 x 10 = 62.8
3.14 is the approximate value of pi. Multiply the diameter of a circle by pi to get its circumference; multiply the square of the radius of a circle by pi to get its area.
The radius of the circle is 4.296739857 and its circumference is 27 feet rounded
you divide the circumference by pi to get diameter then divide that by 2 to get radius then square the radius and multiply it by pi
A circle with a circumference of 43.96 units has:A radius of 6.996 unitsAn area of 153.8 square units
Use the standard formula for the area of a circle to find out the circle's radius. Then multiply that by 2 x pi, to get the circumference.
3.14 is the approximate value of pi. Multiply the diameter of a circle by pi to get its circumference; multiply the square of the radius of a circle by pi to get its area.
r = 9.027 ft C = 56.72 ft
r = 19.54 ft C = 122.8 ft
r = 5.585 ft C = 35.09 ft
r = 34.83 ft C = 218.9 ft
r = 5.597 ft C = 35.16 ft
There is no need to square the answer. The circumference of any circle is 2 radius pi or 2rπ.
The radius of the circle is 4.296739857 and its circumference is 27 feet rounded
you have to quote the diameter or radius or circumference of the circle to calculate the area. If diameter 78.53. If radius 314.15. If circumference 7.95
The answer requires information on the size of the circle: its radius, diameter or circumference.
area of a circle = pi * radius² = 1 radius = √(1/pi) circumference = 2pi * radius = 2pi * √(1/pi) = 3.5449077
A circle with a radius of 80 inches has an area of 139.6 square feet A circle with a circumference of 40.5 feet has an area of 130.5 square feet
