    Answer:  (1) 1437   1/3 cm²

    Explanation:-
    The surface area of sphere = 616 cm²                  (Given)

    Formula-
    The surface area of sphere = 4πr²

    Then, 4πr² = 616
    r² = 616 x 7/22 x 4
    r² = 49
    Square on both side,
    r = 7 cm

    Formula-
    The volume of the sphere = 4 πr³/3

    Then, the volume of sphere = 4 x 22 x 7 x 7 x 7 /3 x 7
    = 4312/3
    = 1437  1/3  cm³

    Hence, the answer is  (1) 1437   1/3 cm³.
