Question

The circumference of Tyler's bike tire is 72 inches. What is the diameter of the tire? Please leave a detailed explanation of how you got your answer!! Thank You!

Answer 1

22.91 inches

Explanation:

circumference = 2πr

2πr = 72 inches

2 x
`(22)/(7)` x r = 72

`(44)/(7)` x r = 72

Solving for r , divide both sides of the equation by 7/44

r = 11.454545 inches

diameter= 2 x radius

2 x 11.454545 inches = 22.91 inches
