    Question

    Find the curved surface area of a cone whose height is 6

    m and radius is 8 m. (in m 2 ) (approximate value) (The value of π is 22/7)
    A 251 Correct Answer Incorrect Answer
    B 274 Correct Answer Incorrect Answer
    C 255 Correct Answer Incorrect Answer
    D 267 Correct Answer Incorrect Answer

    Solution

    Given -h=6m and r= 8m The surface area of the cone = πrl So now – l= √ (36+64) =10 CSA of cone = (22/7) ×8×10 =25.14×10 =251.4 m2 (Approx)
