A container, open from the top, made up of a metal sheet is in the form of a frustum of a cone of height 16 cm with radii of its lower and upper ends as 8 cm and 20 cm respectively. Find the cost of milk which can completely fill the container at the rate of Rs 15 per litre and the cost of metal sheet used, if it costs Rs 5 per 100 cm^(2) . (take pi = 22/7)

A container opened at the top and made up of a meta! sheet, is in the form of a frustum of a cone of height 16 cm with radii of its lower and upper ends as 8 cm and 20 cm respectively. Find the cost of milk which can completely fill the container, at the rate of ? 50 per litre. Also find the cost of meta! sheet used to make the container, if it costs Rs. 10 per 100 cm^2 ? ( Take pi = 3.14).
