    Calculate the volume of a sphere whose diameter measures

    21 cm. (Take π = 22/7)
    A 4851 cm³ Correct Answer Incorrect Answer
    B 9702 cm³ Correct Answer Incorrect Answer
    C 1617 cm³ Correct Answer Incorrect Answer
    D 3234 cm³ Correct Answer Incorrect Answer

    Solution

    Volume of sphere = (4/3) X π X radius3 Radius of the given sphere = (21/2) cm So, required volume = (4/3) X (22/7) X (21/2) 3 = 4851 cm3 Hence, option a.
