Answer:

40π inches, or approximately 125.66 inches

Explanation:

The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle and π is a mathematical constant approximately equal to 3.14.

In this case, the radius of the tire is 20 inches. So, the circumference of the tire is:

C = 2πr

C = 2π(20)

C = 40π

Therefore, the circumference of the tire is 40π inches, or approximately 125.66 inches if you round to two decimal places.
