Finding the circumference of a circle whose area is 452.16 Square meters

Hey user!

your answer is here ...

given the area of the circle is = 452.16m²

therefore πr² = 452.16m²

==> 3.14 * r² = 452.16m²

==> r² = 452.16/3.14

==> r² = 144

==> r = √144

==> r = 12m

the radius of the circle is 12m.

now, circumference of the circle = 2πr

= 2 * 3.14 * 12.

= 75.36m

cheers!
