the curved surface of a right circular cone of height 15 cm and base diameter 16 cm is
sol . h = 14 cm , r = 7 cm . so , l = √ r ² + h ² = √ 8 ² + ( 15 ) ² = 17 cm . ∴ curved surface area = ∏ rl = ( ∏ * 8 * 17 ) cm ² = 136 ∏ cm ² answer c
multiply(const_pi, multiply(divide(16, const_2), sqrt(add(power(15, const_2), power(divide(16, const_2), const_2)))))
