Question

radius of a bicycle wheel is 3meter ,what would be the radius of a cicle whose area is 9 times the area of the first circle?​

Answer 1

Answer:

Step-by-step explanation:

In one turn, a bicycle covers a distance equal to the circumference of it's wheel.

Circumference of a wheel= 2*pi*radius

So, in 3 turns it will cover a distance equal to say ‘d',

d= 3*circumference of a wheel= 3*2*(22/7)*28

= 528 cms

Hence, it travels 528 cms in 3 turns.
