Question 1062444: Tank A is cylindrical with diameter 22 ft and height 12 ft. Tank B is cylindrical with diameter 28 ft and height 18 ft. Both tanks start half full when the pumps are engaged. Pump A fills Tank A at 4.3 ft^3/s while pump B fills tank B at 2.1 ft^3/s. How long must the pumps work until the tanks have the same amount?

You can put this solution on YOUR website!
A, initial volume:
6%2Api%2A11%5E2

B, initial volume:
9%2Api%2A14%5E2

y, the time while both tanks are being filled.
y is in unit, "seconds".
6pi%2A11%5E2%2B4.3y=9pi%2A14%5E2%2B2.1y
If this equation is understood, then you know the rest.
