Base area = 616m sq.
πr^2 = 616
r^2 = 616*7/22
r^2 = 196
r = 14
Radius =14 m
Height = 48 m
CSA of cylinder = 2πrh
=2*22/7*14*48
=5984m sq.

Volume of cylinder = πr^2h
=22/7*14*14*48
=29568m cube

Dear student 
Let me complete the question , ans ans is incomplete.
29568 cubic metre = 29568000 Litre
1 litre cost = 65 paisa = 0.65 Rupees

Hope this helps 
Good Luck
