precalculus- A cylindrical tank with a cross-sectional area of 100 square cm is filled with an area of 10 square cm is opened, allowing water to flow out of the tank. The depth of the water at time t≥0, is d(t)=(10-2.2t)^2.

a) what is the initial volume of water in the tank?
-I'm not quite sure how to find volume out of depth..

b) what is the depth of the water at time t=1 sec.? What is the volume of water at this time?
- d(1)=(10-2.2*1)^2=60.84cm, same as above, not sure how to figure out the volume out of depth.

c) At what time is the tank empty?
d) what is the implied domain?
