A cylindrical tank with height 15m and diameter 2m is being filled with gasoline at a rate of 500L/min. At what rate is the fluid level in the tank rising?(1L = 1000cm^3). About how long will it take to fill the tank?

Simon,

Since 1 L = 1000 cm^{3}, 500 L/min = 500 000 cm^{3}/min. There are 100 cm in a metre so
