Question

A wheel makes 500 rotations to cover a distance of 88 km.Find the radius of the wheel

Answer 1

$<b>Heya mate. (^_-). Solution below.$
====================================

[] Distance covered in 500 rotation = 88 km = 88000 m


=> Distance covered in 1 rotation
= 88000/500
= 176 m


•°• Distance covered in 1 rotation = circumference = 176 m



[] But circumference of any circle = 2πr, where π = 22/7 and r is the radius.

→→→ 2πr = 176

=> 2 × 22/7 × r = 176

=> 44/7r = 176

=> r = 176 × 7/44

=> r = 1232/44

=> r = 28

•°• The radius of the wheel = 28 m.
