Baskeball 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

56.5 inches of material.

Step-by-step explanation:

We have been given that basketball rims have a diameter of 18 inches. We are asked to find the amount of material that we need to put a band around a basketball rim.

The length of the band around rim would be equal to circumference of circle with diameter of 18 inches.

, where r represents radius of circle.

We know that diameter is 2 times radius.    

Upon substituting , we will get:

Therefore, we will need 56.5 inches of material to put a band around the basketball rim.
