Q : 7 A joker’s cap is in the form of a right circular cone of base radius 7 cm and height 24 cm. Find the area of the sheet required to make 10 such caps.
Given, a right circular cone cap (which means no base)
Base radius of the cone =
We know, Curved surface area of a right circular cone
The curved surface area of a cap =
The curved surface area of 10 caps =
Therefore, the area of the sheet required for 10 caps =
