9. A cylindrical water tank 50 ft deep and 25 ft across is used to store pool water for a water park. When the tank is empty, Daniel begins to fill the tank from a garden hose. The rate of flow of water from the garden
hose is 24 gal/min. If Daniel starts filling the tank when he gets to work, and his shift is only 8 hours long,
will he still be working when the tank finishes filling up?

Titus works at a hotel. part of his job is to keep the complimentary pitcher of water at least half full and always with ice. when he starts his shift, the water level shows 4 gallons, or 128 cups of water. as the shift progresses, he records the level of the water every 10 minutes. after 2 hours, he uses a regression calculator to compute an equation for the decrease in water. his equation is w –0.414t + 129.549, where t is the number of minutes and w is the level of water. according to the equation, after about how many minutes would the water level be less than or equal to 64 cups?
