To find the area of a circle from its circumference, you can follow these steps:
-
Find the diameter using the formula for circumference:
\[ C = \pi d \] Therefore, the diameter can be found by dividing the circumference by \(\pi\):
\[ d = \frac{C}{\pi} \] -
Find the radius by dividing the diameter by 2:
\[ r = \frac{d}{2} = \frac{C}{2\pi} \] -
Use the radius to find the area using the area formula:
\[ A = \pi r^2 \]
Given these steps, the correct option is:
C. Divide the circumference by \(\pi\) to find the diameter. Divide the diameter by 2 to find the radius. Use the radius in the formula \(A = \pi r^2\) to find the area.
