Algebra 2 Problem! Can someone please make sure it’s correct?!

Question

What is the area of a circle with a circumference of 4π² ?

(A) 4π²

(B) 16π⁴

(C) 4π³

(D) 4π^3/2

(E) None of the above

I got (E) None of the above. Would this be the correct answer?

Answer 1

Remember that Circumference is 2πr. if 4π² = 2πr, then what is r?

4π² = 2πr → 4π = 2r → 2π = r → radius is 2π

Now I can Solve for the Area which is πr²

π(2π)² → π (4π²) → 4π³
