Radius of given circle "r" = 6 centimeter

Explanation:

Given:

Area of given circle = 36π centimeter²

Find:

Radius of given circle

Computation:

Area of circle = πr²

where r = Radius of given circle

⇒ Area of given circle = πr²

By putting value of "Area of given circle"

⇒ πr² = 36π

BY dividing π from both side

⇒ r² = 36

⇒ r = √36

⇒ r = 6

Radius of given circle "r" = 6 centimeter
