Expert Answer:

begin mathsize 16px style Volume space of space the space rectangular space tank space equals space 28 cross times 16 cross times 11 equals 4928 space straight m cubed
Capacity space of space the space cylindrical space tank space equals space Volume space of space the space rectangular space tank space space... left parenthesis given right parenthesis
rightwards double arrow πr squared straight h equals 28 cross times 16 cross times 11 space space where space straight h equals space depth space of space the space tank
rightwards double arrow 22 over 7 cross times 28 squared cross times space straight h equals 28 cross times 16 cross times 11
rightwards double arrow straight h equals fraction numerator 28 cross times 16 cross times 11 cross times 7 over denominator 28 cross times 28 cross times 22 end fraction
rightwards double arrow straight h equals 2 space straight m
So comma space the space depth space of space the space tank space is space 2 space straight m. end style
