If the circumference of a circle measures 12π cm, what is the area of the circle in terms of π?

So the formula for the circumference of a circle is π x diameter

Since we know the the circumference already, we just divide that by π:

12π / π = 12

Now we halve the diameter to get the radius:

12 / 2 = 6

The area of a circle is π x radius²

So the area is:

·π x 6² = 36π· (or 113 not in terms of π)
