Answer:

  • A = 9π
  • r = 4
  • A = 1/4π
  • r = 10

Explanation:

The given formula can be used to find the area when the radius is known.

r = 3, A = 3²π = 9π

r = 1/2, A = (1/2)²π = 1/4π

The formula can be solved to give the radius when the area is known:

r = √(A/π)

A = 16π, r = √(16π/π) = 4

A = 100π, r = √(100π/π) = 10
