Question

Priya rode her bike 1250 feet. If her bike wheel has a diameter of 2.5 feet, how many times did her wheel make a full rotation?

Answer 1

159 times

Explanation:

Since her bike has a diameter of 2.5 ft and her wheel makes full rotation each time, we can calculate the circumference of rotation using the equation of circumference of a circle.

C = πd

C = π(2.5)

C = 7.855 ft

If Priya rode her bike 1250 feet, the number of times her wheel makes ful rotation = Total distance rode/circumference of one rotation

= 1250/7.855

= 159.13

This means Priya's wheel make a full rotation 159 times
