Question

Basketball rims have a diameter of 18 inches. If you want to put a band around a basketball rim, how much material to the nearest tenth of an inch will you need?

Answer 1

You would need 18`pi` inches of material, or 56.5 inches if rounded to the nearest tenth of an inch.

Explanation:

The formula for circumference is `pi`d, meaning pi (~3.14) times the diameter of the circle. Plugging in 18 for d, you get `pi`(18), which equals 56.548667...

You specified it needed to be rounded to the nearest tenth of an inch, so you'd round that to 56.5 inches.
