A container open at the top is in the form of a frustum of a cone of height 17 \(cm\) with radii of its lower and upper ends are 9 \(cm\) and 22 \(cm\) respectively. Find the cost of milk which can completely fill a container at the rate of \(₹43\) per litre.
Answer:
Volume of the frustum of a cone is given by cu.units.
Capacity of the container \(=\) \(cm^3\)
[Note: Enter the answer upto three decimal places.]
We know that, \(cm^3 = 1\) litre.
Thus, the cost of milk that will fill the container \(=\) \(₹\)
[Note: Round off the cost to two decimal places.]
