Question

A wheel made 72 revolutions. It has a radius of 23 cm. How far did it travel?
PLS ANSWER....

Answer 1

Answer:

Here,

Radius, R = 23 c.m

A wheel travels equal its circumference in every rotation.

Circumference, C = 2πR = (2 × 3.1416 × 23) c.m = 144.5136 c.m

For 72 revolution, it will travel = 72 × C = (72 × 144.5136) c.m = 10404.9792 c.m

Now,

100 c.m = 1 m

1 c.m = (1/100) m

So, 10404.9792 c.m = (10404.9792/100) m = 104.049792 m

So, it will travel about 104.049792 m
