The answer depends on whether 8 foot refers to the radius or diameter.
2 x pi x 8 ft = 50.265 ft
It is: 2*pi*8 = 50.265 feet rounded to three decimal places
the circumference is two times the radius, or 2r. so if the radius was 3, the circumference would be 6. if the radius was 4, the circumference is 8.
The circumference of a circle with an 8 cm radius is: 50.27 cm
If the radius of a circle is 8 feet the circumference is about 50.27 feet.
The circumference of circle with 2 foot radius is: about 12.57 feet. (c = r x 2 x Pi)
The circumference of a circle with a 4-foot radius is about 25.13 feet. (C = r x 2 x Pi)
A circle with a radius of 8 inches has a circumference of 50.27 inches.
The circumference is 175.92918860102841 feet.
circumference = 2*pi*100
Circumference = 2*pi*radius So Radius = Circumference/(2*pi) = 8/(2*pi) = 4/pi = 1.2732 (to 4 dp)
