A container made up of a iron is in the form of a frustum of a cone of height \( 16 \mathrm{~cm} \) with radii of its lower and upper ends as \( 8 \mathrm{~cm} \) and \( 20 \mathrm{~cm} \) respectively. Find the cost of the diesel which can completely fill the container at the rate of ₹ 104 per litre and the cost of the iron sheet used, if it costs ₹ 45 per 100 \( \mathrm{cm}^{2} \). (Take \( \pi=3.14 \) )
