Problem: A wheel makes 1000 revolutions in covering a distance of 88 km. Determine the diameter of the wheel.

View all: UCBL BANK | OFFICER | WRITTEN MATH QUESTION SOLVE | 2010

Correct Answer: 28 m

Explanation:

In 1000 revolutions the wheel cover = 88 km

In 1 revolutions the wheel cover =88 m

Let, diameter of the wheel is 2m

Circumference = 2πr = 88

=> 2r =$\frac{88}{π}$

The diameter of the wheel = $\frac{88}{π}$meter= 28 meter
