What is the radius of a circle having the circumference 22cm. Solve step by step plzz​

3.5cm = r

Explanation:

2πr = Circumference Formula

22cm = Circumference

Using Formula,

We get,

22 = 2πr

22 = 2 x 22/7 x r

11 = 22/7 x r

77 = 22 x r

77/22 = r

7/2 = r

3.5 = r

Explanation:

let radius of a circle be x

circumference=2πr

22=2*3.14*r

22=6.28*r

22/6.28=r

3.50=r

3.6=r
