Answer 2

Answer:

  (c)  4 in

Step-by-step explanation:

The area of a circle is given by the formula ...

  A = πr²

Filling in the given values, we have ...

  16π in² = πr²

Dividing by π gives ...

  16 in² = r²

Taking the square root, we find ...

  r = √(16 in²) = 4 in

The radius of the circle is 4 inches.
