Question
Calculate the lateral surface area of a right circular cone
whose diameter is 14 cm and vertical height is 10 cm.Solution
ATQ,
Radius of the cone = (14/2) = 7 cm
So, slant height of the cone = √(10² + 7²) = √(100 + 49) = √149 cm
So lateral surface area of the cone = π × radius × slant height = 7π√149 cm²
