Question

if the circumference of a circle is 264 cm find its radius take pi =22 by 7.

Answer 1

2pi x r = 264
Pi x r = 132
R = 132 x 7 by 22
R = 42 cm

Answer 2

Circumference of wheel is 2πr or πd

Now according to the formula

264 cm = πd

264/π = d ( Take either 22/7 or 3.14, it depends upon you )

84.0338/2=42.01
answer is 42.01
