Question

A wheel makes 1000 revolutions in covering a distance of 88 km. Find the radius of the wheel.

Options:

A . 14 m.

B . 15 m

C . 16 m

D . 17 m

Answer: Option A

Distance covered in one revolution =` ((88 xx 1000)/(1000))` = 88 m.

`:.` `2 pi R ` = 88

`hArr 2 xx 22/7 xx R = 88`

`hArr R = (88 xx 7/44)` = 14 m.
