Given the area of a circle is 12pi.

Then we will calculate the radius using the circumference formula.

==> C = 2* pi *r = 12 pi

==> r = 12pi/2pi = 6

Now we will calculate the area of the circle.

==> We know that A= r^2 * pi

==> A = 6^2 * pi = 36 pi = 113.1 ( approx)

**Then the area of the circle whose circumference 12pi = 36pi = 113.1 square units.**

The circumference of a triangle is given by 2*pi*r where r is the radius and the area is pi*r^2.

Here circumference = 12*pi = 2*pi*r

=> r = 6

The area = pi*r^2 = 36*pi

**The area of the circle is 36*pi**

HERE IT IS GIVEN THAT,

CIRCUMFERENCE of the circle = 12pi

Now we can find the radius of the circle by using the formula,

circumference ,(C) =2 x pi x r

We can rewrite it as,

==> 12 x pi = 2 x pi x r

==> r = 12/2

==> r = 6 units

now, we have the radius of the circle(r) = 6 units

WE CAN FIND THE AREA OF THE CIRCLE BY USING THE FORMULA,

area of the circle(a) = pi x r^2

Therefore, ==> a = pi x 6^2

==> a = 36pi

**Hence, the area of the circle is 36pi. Which is equal to (36 x 22/7)= 113.14 .**
