Question

Find the radius if the circumference is 132cm.​

Answer 1

Step-by-step explanation:

Circumference of a circle of radius r =2πr=132cm

2×7/22× r=132cm

r=21cm

Answer 2

Answer:

21.02 cm

Step-by-step explanation:

Let, the radius of the circle x

∴ According to the formula,

           the circumference of the circle is = 2 * π * x = 132

                                                                  => x = $\frac{132}{2*3.14}$

                                                                  => x = 21.02 cm.
