- A conical water tank with its vertex at bottom has radius 20m and depth 20m.Water is being pumped into the tank at rate 40m^3/min.how fast is the level of the water rising when water is 8m deep? ( v=(pi x r² x h)/3 )
- A conical tank (with vertex down) is 10 feet across the top and 12 feet deep. Water is flowing into the tank at a rate of 5 cubic feet per minute. Find the rate of change of the depth of the water when the water is 4 feet deep.?
- Gasoline is pumped from the tank of a tanker truck at a rate of 20L/s. If the tank is a cylinder 2.5m in diameter and 15m long, at what rate is the level of gasoline falling when the gasoline in the tank is 0.5m deep?
- I'd need help with the whole question..but even just in part 9i, the answer is d(theta)/d(t)=kt. Where does the t come from?? It's simple things like this which confuse me.. Thanks for your help!!

- How fast is the water level rising when the water is 3 cm deep (at its deepest point) if water is poured into a conical container at the rate of 10 cm3/sec. the cone points directly down, and it has a height of 25 cm and a base radius of 15 cm?
- Water is leaking out of an inverted conical tank at the rate of 10,000cm^3/min cm/min at the same time that water is being pumped into the tank at a constant rate. The tank has a height of 6m and the diameter at the top is 4m. If the water level is rising at a rate of 20 cm/min when the height of the water is 2m, how can I find the rate at which water is being pumped into the tank.?
