please solve it urgently. 15.A milk contractor supplies a total Of 1000 litre of milk in two vessels each having a height equal to 95 cm One vessel is cylindrical having a base radius equal to 40 cm and the other has a square base Of each side 72 cm. The contractor claims that either of the two vessels Contains 500 litres Of milk_ The school management applies 3 % cut on the amount to be paid to the milk contractor Is the school management justified in ksser payment? b Comrnent on the dealings Of the milk contractor

V(cylindrical vessel) = pi(r)^2(h) = pi(40)(40)(95) = 477,522.0833 cu.m = 477.522 L       [ 1L = 1000 cu.cm]
V(cuboidal vessel ) = lbh = (95)(72)(72) cu.cm = 492,480 cu.cm = 492.480 L                  [ 1L = 1000 cu.cm]
V(TOTAL) = 970.002 L < 1000 L
a) The 3% cut made by the school management is justified as neither of the containers hold 500 L of milk and the contractor, voiding his contract, supplies less than 1000 L of milk.
b) The contractor tried to swindle the school management by making a contract of 1000 L of milk supply, supplying less than that and lying about his doings.
    This is unacceptable and people must be careful about such activities by such individuals.
