Question

Teresa races her bicycle for 62m. A wheel of her bicycle turns 31 times as the bicycle travels this distance. What is the diameter of the wheel?

Answer 1

Divide the total distance by the number of turns:

62m / 31 turns = 2 meters per turn.

This means the circumference of the tire is 2 meters.

To find the diameter when you know the circumference, divide by PI:

Diameter = 2 / 3.14

Diameter = 0.6369 meters. (Round the answer as needed)
