I don't understand how to solve this problem. Please explain and show me how step-by-step. tHANK YOU!

  • math -

    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.

  • math -

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

  • math -

    r = 4 means the radius equals 4 inches.

    The diameter is twice the radius.
