Question

A spoke of a wheel makes 32 revolutions while the wheel goes 425 feet. Find the approximate radius of the wheel.

Answer 1

The answer is 2 ft.

Answer 2

2.11 ft

Explanation:

Given in the question,

number of revolution a wheel make = 32

distance that wheel traveled while rotating = 425ft

Step 1

Find the circumference of the wheel

circumference = total distance covered / number of revolution

= 425 / 32

= 13.28 ft

Step 2

Formula of circumference

2πr = 13.28 ft

r = 13.28/2π

r = 2.11 ft
