Question 8
Write ‘True’ or ‘False’ and justify your answer in the following
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

Answer 1

The given statement is true.
Because the resulting figure is

Here, ABCD is a frustum of a cone and CDEF is a hollow cylinder.
So, the total area = curved surface area of frustum of a cone + area of circular base + curved surface area of cylinder
