Now that WWE is coming to an end, Howard is building a wrestling arena in his backyard to nurture the new wrestling craze. If the diameter of his circular arena is 20 ft, how many feet of fencing does he need to make the border of the ring?

A 62.80 feet.

To find the amount of fencing Howard needs to enclose the border of the circular wrestling ring, we need to calculate the circumference of the ring. The circumference of a circle can be found using the formula:
Circumference = π * diameter where π (pi) is a mathematical constant approximately equal to 3.14159.

Given that the diameter of the circular arena is 20 ft, we can calculate the circumference as follows:
Circumference = π * 20 ft ≈ 3.14159 * 20 ft ≈ 62.8318 ft

Therefore, Howard needs approximately 62.8318 feet of fencing to make the border of the wrestling ring.
