Question

How many times a wheel of radius 30 cm must rotate to go 250 m?

Answer 1

Answer:

132.58 (Apr.)

Step-by-step explanation:

To find the number of Times wheel needs to Rotate,

We have to first find its Circumference,

Circumference = 2πr =2 * 22/7 * 30 = 2 * 22/7 * 30 = 1320/7

Times wheel should rotate = 250 / (1320/7) * 100 = 132.58 (Apr.)
