      Question

      Determine the curved surface area of a right circular

      cone whose height is 23 cm and diameter of the base is 46 cm.
      A 529π√2 cm² Correct Answer Incorrect Answer
      B 729π√2 cm² Correct Answer Incorrect Answer
      C 249π√2 cm² Correct Answer Incorrect Answer
      D None of these Correct Answer Incorrect Answer

      Solution

      ATQ, Curved surface area of a cone = π × r × x {Where 'x' is the slant height and 'r' is the radius of the cone} x2 = 232 + (46/2)2 Or, x2 = 529 + 529 Or, x = 23√2 cm So, required area = π × 23 × 23√2 = 529π√2 cm2
