Question

Trevor needs new bike tires. His bike tires have a circumference of about 113.04 inches. What is the diameter of his tires?

Answer 1

36 inches

Explanation:

The formula for circumference is 2(pi)r, so first you would divide by 2, which is 56.52 (about) then divide by pi and you get 18. So the radius is 18, so multiply 18 by 2 and you get 36.
