If C = 12, what is the area of the circle?
To find the area of a circle, you can use the formula A = πr^2, where r is the radius of the circle.
If the circumference of the circle is equal to 12, you can use the formula C = 2πr to find the radius.
12 = 2πr
r = 12 / 2π
r ≈ 1.91
Now that you have found the radius, you can calculate the area of the circle:
A = π(1.91)^2
A ≈ 11.46
Therefore, the area of the circle is approximately 11.46.
