Question

A wheel has diameter 84 cm how many complete revolutions it should take to cover 792 metres

Answer 1

Solution:-

Given:-

Diameter of Wheel = 84 cm = 0.84 m

Distance = 792 m.

Circumference of the wheel = 2πr

=) Circumference = 2 × 22/7 × 0.84/2

=) Circumference = 22 × 0.12

=) Circumference = 2.64 m

Now, We know that,

Number of Revolution = Distance/ Circumference.

=) No. of Revolution = 792/2.64

=) No. of Revolution = 300.

Hence,

The wheel will cover 300 Complete Revolutions to cover 792 metres.
