  1. V = pi * r^2 * h
    V = 3.14 * 3.5 * 3.5 * 2
    V = _________ cubic inches of the round pan

    V = L * W * H
    V = 9 * 6 * 2
    V = ________ cubic inches of the rectangular pan

    A = pi * r^2
    A = L * W

  3. You're welcome.

    I just realized you need to do a further calculation for b. I only figured the frosting needed for the top. You need to figure the sides of the cake also.
