A cylindrical tank that is 30 feet high with a radius of 5 feet is filled with water. At time t = 0, water is pumped out of the spigot at a rate of r(t) = (130 – 5t) feet/minute. a. How long will the water continue to be pumped at this rate? %3D b. Using the time calculated in part a. above, determine the total volume of water pumped and the depth of the water in the container when pumping is complete.
