Question

find the diameter of a wheel whose circumference is 264 CM

Answer 1

Let the radius of the wheel be r

Then its circumference = 2 × pi × r = 264 cm.

So,2 ×pi ×r =264 cm

So,r =(264/2 × 7 /22) cm

=( 84/2 ) cm

=42 cm

Radius = 42 cm.

And,Diameter = (42×2)cm

=84 cm

So , diameter of the wheel whose circumference is 264 cm = 84 cm
