# In covering a distance s metres, a circular wheel of radius r metres makes s2πr revolutions. Is this statement true? Why? - Mathematics

MCQ
True or False

In covering a distance s metres, a circular wheel of radius r metres makes s/(2 pir) revolutions. Is this statement true? Why?

• True

• False

#### Solution

This statement is True.

Explanation:

The distance travelled by a circular wheel of radius r m in one revolution is equal to the circumference of the circle =2pir

No. of revolution completed in 2pir distance = 1

No. of revolution completed in 1 m distance = 1/(2pir)

No. of revolution completed in s m distance = (1/(2pi)) xx s

= s/(2pir)

Concept: Circumference of a Circle
