      Question

      Find the curved surface area of cone whose height is 3 m

      and radius is 4 m.  (approximate value) (The value of π is 22/7)
      A 62.5 m² Correct Answer Incorrect Answer
      B 33 m² Correct Answer Incorrect Answer
      C 45 m² Correct Answer Incorrect Answer
      D 79 m² Correct Answer Incorrect Answer

      Solution

      Given -h=3m and r= 4m The surface area of the cone = πrl So now – l= √ (9+16) =5 CSA of cone = (22/7) ×4×5 =12.5×5 =62.5 m2 (Approx)
