Answer 1

Answer:

Rs. 58,496,455.21

Step-by-step explanation:

Volume of cylinder = pi*r^2*h

                                = pi* 7^2*20

                                =980pi cubic cm

volume of cone = 1/3*pi*r^2*h

                          = 1/3*pi*7^2*3

                          =49pi cubic cm

volume of vessel = 980pi - 49pi = 931pi cubic cm

1 cubic cm = 1000 l

931pi cubic cm = 2924822.76 l

cost = 1 l = Rs. 20

2924822.76 l = Rs. 58,496,455.21
