A circle of area 27pie^2 must have a radius what is the answer?

Question

A circle of area 27pie^2 must have a radius what is the answer?

Answer 1

Area = (pi) r^2

27(pi)^2 = (pi) r^2

27(pi)=r^2

sqrt(27(pi))= r  =sqrt ((9x3)(pi)) = 3(sqrt 3)(sqrt pi)

3 (sqrt 3)(sqrt pi) or approx. 9.21 to three significant figures

Answer 2

A = pi * r^2

27pi^2 = pi * r^2

27pi = r^2

root(27pi) is your answer, assuming you meant 27 * (pi)^2

If you meant (27pi)^2, then the answer is (27pi) / root(pi)

Answer 3

27(pi)(r)^2

r=27

Answer 4

Area = 27 pi^2 = pi r^2

=> r = sqrt{27pi}
