72 foot
Distance around circle = 2*pi*r = 157.1 so r = 157.1/(2*pi) = 25.00 ft so, to the nearest tenth of a foot, 25.0 ft
If the diameter (distance across) the circle is 8.5 feet, then multiply that by pi (3.14) to get the circumference (distance around the outside)

The radius of a circle is half the length of the diameter. Therefore, if the diameter is 1 foot, the radius would be 0.5 feet. This is because the radius is the distance from the center of the circle to any point on the circle's circumference, while the diameter is the distance across the circle passing through the center.
Circumference of a circle = 2*pi*radius or pi*diameter
Distance around circle = 2*pi*r = 157.1 so r = 157.1/(2*pi) = 25.00 ft so, to the nearest tenth of a foot, 25.0 ft

Area of a circle = pi*radius squared
Area of a circle = pi times radius squared

That depends on whether the "8 feet" refers to the radius, the diameter, or the circumference of your round area.What in the world is "an 8 foot round area" ?Is 8-ft the "diameter", the distance through the center of the circle ?Is it the distance all the way around the curvy part of the circle ?Is this area even a circle ?IF this is a circle, and IF the distance around it is 8-ft, then its area is 5.093 square feet.If the diameter is 8-ft, then its area is 50.265 square feet.
A 25-foot radius circle is 1,963.5 ft2
