144 pi
you sure?
Yes, I am sure.
Since the formula for the area of a circle is A = πr^2, where r is the radius of the circle, and in this case C = 2πr (where r is the radius),
we can find the radius by dividing C by 2π.
So, r = C / 2π = 12π / 2π = 6.
The area of the circle is A = π * (6)^2 = π * 36 = 36π.
Thus, the area of the circle is 36π.

The area of the circle is A = π * (6)^2 = π * 36 = 36π.
Thus, the area of the circle is 36π.
so is the answer 144 or 36
Apologies for the confusion. Let me correct my earlier response.
Given that C = 12π, we can use the formula for the circumference of a circle: C = 2πr, where r is the radius of the circle.
By rearranging the formula to solve for the radius (r), we get r = C / (2π) = 12π / (2π) = 6 units.
Now, using the formula for the area of a circle, A = πr^2, the area of the circle is A = π * 6^2 = 36π.
Therefore, the correct answer is 36π. Thank you for pointing that out.
