Question

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

Answer 1

56.5 inches of material.

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.

`\text{Circumference of circle}=2\pi r`, where r represents radius of circle.

We know that diameter is 2 times radius.

`D=2r`

`\text{Circumference of circle}=\pi D`

Upon substituting
`D=18\text{ inches}`, we will get:

`\text{Circumference of circle}=\pi (18\text{ inches})`

`\text{Circumference of circle}=56.548667\text{ inches}`

`\text{Circumference of circle}\approx 56.5\text{ inches}`

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