Hello mate,
Here is your solution==>>
<================================>
R = 20 cm ; r = 8cm ; h =24cm ; cost of milk/L = 21 rs.
volume of frustum = volume of milk
= 1 /3 * 22 / 7 * 24 * (202+82+ 20*8)
= 22 / 7 * 8 *624
= 109824 / 7 cm3
1000 cm3= 1 L
= 109824 / 7 *1 / 1000
and, 1L =21 rs.
= 109824 / 7000 * 21
= 2306304 / 7000
= 329.472 rs.
Therefore,
Total cost of filling = 329.472 rs.
