# How much distance, in metres, a wheel of 25 cm radius will cover if it rotates 350 times?

**Solution:**

It is given that

__Radius__ of wheel = 25 cm = 25/100 m = 1/4 m [As 1 cm = 1/100 m]

We know that

Distance traveled in one rotation = 2πr

Substituting the values

= 2 × 22/7 × 1/4

= 11/7 = 1.57 m

Therefore,

Distance traveled in 350 rotations = 1.57 × 350

= 550 m

Therefore, the wheel covers a distance of 550 m.
