  1. You need to find the diameter of each pie.

    You know the area.

    A = pi * r^2
    50.24 = 3.14 * r^2
    50.24 / 3.14 = r^2
    16 = r^2
    4 = r

    Each pie has a diameter of 8 inches.

  2. wait then what is the 4 for? please explaina little more

  3. r = 4 means the radius equals 4 inches.

    The diameter is twice the radius.
