If the perimeter of a square is 44 cm , then find the perimeter of a circle whose radius is equal to the length of a side of the given square.

Correct option is A

Given:

Perimeter of square = 44cm

Formula Used:

Circumference = $$2\pi r$$​​

Perimeter of square = 4a

Solution:

Perimeter = 4a = 44

a= 11cm

Radius of circle = 11cm

Circumference of circle =$$2\pi (11) = 22\pi$$​​
