Surface Area of a Frustum

State True1 o...

Question

State True(1) or False(0).

An open metallic bucket is in the shape of a frustum of a cone, mounted on a hollow cylindrical base made of the same metallic sheet. The surface area of the metallic sheet used is equal to curved surface area of frustum of a cone + area of circular base + curved surface area of cylinder

Open in App

Solution

Surface area of the used metallic sheet = curved surface area of frustum of a cone + area of circular base + curved surface area of cylinder.
Hence true.
