    B 42cm Correct Answer Incorrect Answer
    C 72cm Correct Answer Incorrect Answer
    D 68cm Correct Answer Incorrect Answer

    Solution

    The volume of a solid hemisphere =2/3 πr3 2/3 πr3   = 155232 2/3 ×22/7 ×r3 = 155232 r3= 3528×21 =441×8×21 r=21×2= 42           Then diameter of solid hemisphere = 42 ×2=84cm
