Question

A wheel covers 110m in one revolution. What is its radius?

Answer 1

Hey friend...!!!

Circumference = 110 M
so,2 × 22/7 × r = 110
44/7r = 110
r = 110 × 7/22
r = 17.5m

so, its radius = 17.5 m

hope it helps...!!!

Answer 2

Given:

Distance covered by a wheel in one revolution is 110 m.

To Find:

The radius of the wheel.

Solution:

The distance covered by the wheel in one revolution is equal to the circumference of the wheel.

2πr = 110

where, r is the radius of the wheel.

Therefore,

r = 110 / 2π

r = (110 × 7) / (2 × 22)

r = 770 / 44

r = 17.5 m.

The radius of the wheel is 17.5 m.
