    Question

    Determine the slant height of a cone with a height of 20

    cm. The cone's base radius is the same as that of a sphere, which has a volume of 38,808 cm┬│. (Use ╧А = 22/7)
    A 27 cm Correct Answer Incorrect Answer
    B 33 cm Correct Answer Incorrect Answer
    C 25 cm Correct Answer Incorrect Answer
    D None of these Correct Answer Incorrect Answer

    Solution

    Volume of a sphere = (4/3) X ╧А X r3┬а(Where 'r' is the radius) So, (4/3) X (22/7) X r3┬а= 38,808 Or, r3┬а= 38,808 X (21/88) Or, r3┬а= 9,261 So, r = 21 cm Slant height = тИЪ(height2┬а+ radius2) = тИЪ(202┬а+ 212) = тИЪ(400 + 441) = тИЪ841 = 29 cm
