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.
To find the radius of a circle, divide the circumference by 2ฯ (approximately 6.28). Therefore, the radius of the circle with a circumference of 232.4 inches is 36.9 inches (232.4 / 6.28).
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

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.
254.47 square inches.
Area = Pi(r)2 - A circle with a radius of 12 inches has an area of 452.39 square inches.
First we have to find the radius: 2*pi*radius = 18*pi Divide both sides by 2*pi to find the radius: radius = 9 inches Area of a circle = pi*radius2 Area = pi*92 = 81pi or 254.4690049 square inches
