    Question

    What is the volume (in cm3) of the metal used

    to make a spherical shell whose inner and outer radii are respectively 5 cm and 8 cm?
    A 524Ï€ Correct Answer Incorrect Answer
    B 576Ï€ Correct Answer Incorrect Answer
    C 516Ï€ Correct Answer Incorrect Answer
    D 476Ï€ Correct Answer Incorrect Answer

    Solution

    Volume of metal used to make a spherical shell = (4/3) X π X (R3 - r3) {Where 'R' and 'r' is the outer and inner radius of the spherical shell, respectively} = (4/3) X π X (83 - 53) = (4/3) X π X (512 - 125) = (4/3) X π X 387 = 516π cm3
