Answer True

Solution

According to the question, here is a metallic bucket 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 Figure (A) is the surface area of (a), (b), (c)

            (a) = curved surface area of frustum

            (b) = area of circular base

            (c) = curved area of cylinder

            Total surface area = curved surface area of a frustum of cone + area of circular base + curved surface area of the cylinder.

            So the given statement is True.
