Question
Calculate the lateral surface
area of a right circular cone having a radius of 5 cm and a height of 12 cm.Solution
Given, Radius of the cone = 5 cm Height of the cone = 12 cm So, slant height of the cone = √(12² + 5²) = √(144 + 25) = √169 = 13 cm Thus, the lateral surface area of the cone = π × radius × slant height = π × 5 × 13 = 65π cm²
