Area of the circle is 24
cm^2.
We have to find the circumference of the
circle.
We use the formula for area A and circumference
C:
A = pi*r^2 and
C = 2pi*r,
where r is the radius of the circle.
So pir^2 = 24 cm^2
given.
r^2 = (24/pi). So r =
(24/p)^(1/2).
We put r = (24/pi)^(1/2) in C = 2pi*r and
get:
So C = 2pi*r. So C = 2pi* (24/pi)^(1/2) =17.3664 cm
nearly.
Therefore the circumference = 17.
3664 cm.
