Find the area of a circle givien c= 4TT give your answer in terms of TT

Answer 1

The formula for the area of a circle is A = πr^2. Given that c = 4π, we can find the radius (r) using the formula c = 2πr:

4π = 2πr
r = 4π / 2π
r = 2

Now that we have the radius, we can find the area of the circle by plugging it into the formula:

A = π(2^2)
A = 4π

Therefore, the area of the circle is 4π.
