452.38 feet = circumference
1.) Formula for circumference (perimeter) of a circle = 2 x pi x radius OR pi x diameter
(because 2 x radius = diameter)
2.) Pi = 3.1415
3.) 2 x 3.1415 x 72 feet = 452.38 feet

Yes. Circumference is the distance around the circle, diameter is the distance across, and radius is the distance from the edge to the center.
The radius is the distance from the edge to the center. Diameter is distance from one edge through the center to the other edge. The diameter is twice the radius. If the radius is 1, then twice that is 2.
Nope. Half the diameter is the radius. Circumference is the distance around the edge.
The radius is the distance from the centre point to the edge.
