    56.56 in³

    Step-by-step explanation:

    This problem bothers on the mensuration of solid shapes, a cylinder

    To solve this problem we need to calculate the volume of both cake pans

    Given data

    First cake pan

    Diameter d = 10in

    Radius r = 5in

    Height h = 2in

    Second pan

    Diameter d = 8in

    Radius r = 4in

    Height h = 2in

    Volume of first cake pan

    V=πr²h

    V = 3.142*5²*2

    V = 157.1 in³

    Volume of second cake pan

    V=πr²h

    V = 3.142*4²*2

    V = 100.544 in³

    Difference in volume is

    =157.1-100.544

    = 56.56 in³
