Question
A right circular cone has a base radius of 9 cm and a
height of 12 cm. Calculate the curved surface area of this cone.Solution
Slant height of the cone = √{(radius)2 + (height)2} = √(92 + 122) = √(81 + 144) = √225 = 15 cm So, curved surface area of the cone = π X radius X slant height = 135π cm2
