Question

can you say the radius if circumference is 132cm . Please do show working out. please do answer.

Answer 1

Step-by-step explanation:

Circumference = 132 cm

We know,

the circumference of a circle = 2 $\pi$ r                  [ r stands for radius ]

So,

Circumference = 2 $\pi$ r = 132 cm

                        => 2 x ( 22/7 ) x r = 132                [  $\pi$ = 22/ 7]

                        => r = ( 132 x 7 ) / ( 2 x 22 )          [ 132 ÷ 44 = 3 ]

                        => r = 3 x 7  

                        => r = 21 cm       ( Ans )

HOPE THIS IS HELPFUL !!! : )
