Q6 of 59 Page 122

In covering a distance s m, a circular wheel of radius r m makes revolution. Is this statement true? Why?

True

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


∴ No. of revolutions completed in 2πr m distance = 1


No. of revolutions completed in 1 m distance = (1/2πr)


No. of revolutions completed in s m distance = (1/2πr) × s
