Radius of circle: 10/2 = 5 feet
A circle with a radius of 5 feet has a circumference of 31.4 feet.
Area of circle: pi*5^2 = 25*pi square feet
circumference = 2*pi*5 feet
78.5 square feet.
The circumference is pi times the diameter of the circle. Diameter is twice the radius, so the diameter is 10 feet. With pi approximately 3.14, the circumference (linear feet perimeter) is 31.4 feet.
If the diameter is 5 feet then the radius is 2.5 feet. If the circumference is 5 feet then the radius is 0.79577 feet.
The circumference of a circle with radius 5 feet is about 31.42 feet.
