Question

Susan has a new mountain bike. For each mile that she rides her bike, her front tire rotates one complete turn approximately 776.1 times. What is the circumference, in inches, of the front tire of Susan’s bike?

Answer 1

1 mile = 5,280 feet

5,280 feet x 12 = 63,360 inches

To find the circumference, did ie total inches by rotations:

63,360 inches / 776.1 rotations = 81.6389 inches.

The circumference of the tire is 81.6389 inches. (Round the answer as needed)
