I need help with these questions

a.

This question is a rather odd way to ask you to find the radius of a circle from its area.

A = π r²

40000 = π r²

r² = 40000/π

r = √(40000/π)

r ≈ 112.8379

 113 miles

b.

C = 2 π r

754 = 2 π r

r = 754/2π = 377/π

A = π r² = A = π (377/π)² = 377²/π

A ≈ 45241.0658

45241 square miles
