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

Answer:

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.

$\text{Circumference of circle}=2\pi r$, 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.
