Find the curved surface area of a right circular cone whose slant height is 10 cm and base radius is 7 cm.

  • 1

Using base radius r = 7 cm and slant height l = 10 cm, the curved surface area formula πrl gives (22/7) × 7 × 10 = 220 cm².

    1. The base radius of the right circular cone is given as r = 7 cm and its slant height is l = 10 cm. The curved surface area is given by the formula CSA = πrl. Substituting the given values using π ≈ 22/7, we calculate CSA = (22/7) × 7 × 10 = 220 cm².
