Question

Is it true that the distance travelled by a circular wheel of diameter d cm in one revolution is 2 π d cm? Why?

Options

• True

• False

Answer 1

This statement is False.

Explanation:

Distance travelled by a circular wheel of radius r in one revolution equals the circumference of the circle.

We know that,

Circumference of the circle = 2πd; where d is the diameter of the circle.

Thus, it is not true that the distance travelled by a circular wheel of diameter d cm in one revolution is 2 d cm.
