Question 7 Angles Exercise 11.2

A bicycle wheel makes four and a half turns. Find the number of right angles through which itturns.

Answer:

We know that the wheel of a bicycle covers 360o in one turn.

It can be written as

360/90 = 4 right angles

We know that in four and half turns the wheel turns by 4 (4.5) = 18 right angles

Hence, the number of right angles through which it turns is 18.
