divide the circumference by 3.14 to get the diameter - then divide that by 1/2 to get the radius
Radius = Circumference / 2 x pi from C = Diameter x pi
radius = circumference/2*pi
find the circumferance as if it was a whole circle but when you get the answer divide it by 2
A circle with a radius of 8 inches has a circumference of 50.27 inches.
The radius of a circle with a circumference of 232.4 inches is 37 inches.
The radius of a circle is half of the diameter! So, if the diameter was four inches, the radius would be two inches!
radius = circumference/2*pi

A circle with a radius of 8 inches has a circumference of 50.27 inches.
The radius of a circle with a circumference of 232.4 inches is 37 inches.
Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
The approximate radius is five (5) inches.
The radius of a circle is half of the diameter! So, if the diameter was four inches, the radius would be two inches!
radius = 20/(2*pi) = 3.183098862 inches
Area = Pi(r)2 - A circle with a radius of 25 inches has an area of 1,963.5 square inches.
The radius of a circle is half of its diameter. Therefore, if the diameter of the circle is 60 inches, the radius would be half of 60, which is 30 inches. The formula to find the radius from the diameter is: radius = diameter / 2.
254.47 square inches.
Area = Pi(r)2 - A circle with a radius of 12 inches has an area of 452.39 square inches.
