Expert Answer:

Tank
total space height space equals space 4.2 space straight m
radius space of space cylinder space equals space 0.6
height space of space cylinder space equals space 4.2 space minus 0.6 minus 0.6 equals 3
total space volume space equals space vol. space of space cylinder space plus space 2 cross times vol. space of space hemisphere
equals straight pi open parentheses 0.6 close parentheses squared 3 plus 2 cross times 2 over 3 cross times straight pi cross times 0.6 cubed
equals 3762 over 875 straight m cubed
container space volume equals straight pi open parentheses 21 over 100 close parentheses squared cross times 15 over 100 equals 0.02079 straight m cubed
60 space containers equals 1.2474 straight m cubed
Water space left equals 3762 over 875 minus 1.2474 equals 3.0520 space straight m cubed equals 3052 space liters
