Answer 1

The formula for finding the area of a circle is A = πr², where r is the radius of the circle.

Since C = 2πr (circumference formula), and C = 4π in this case, we can solve for r:

4π = 2πr
r = 4π / 2π
r = 2

Now that we have the radius, we can plug it into the area formula:

A = π(2)²
A = 4π

Therefore, the area of the circle is 4π.
