The formula is: C = 2πr or 2pi*r
so, 2*3.14*8 = 50.24 inches.

Actually, pi is bigger than 3.14 and, if you intend to give your answer to 2 decimal places, you must use pi to greater precision. A more accurate answer - to 2 decimal places - is 50.27 inches.
The radius is 8 inches.
A circle with a radius of 8 inches has a circumference of 50.27 inches.
Radius of circle: 16/2 = 8 inches
8 inches; the diameter of a circle is twice its radius.
Radius of circle: 8/2 = 4 inches
A circle with a radius of 8 inches has a circumference of 50.27 inches.
Radius = 8/2 = 4 inches
The radius will be half the diameter of 8 inches which is 4 inches
Radius = 16/2 = 8 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.
