A spherical tank has a radius of 6 feet. Frankie filled the tank with gasoline at a rate of 23 cubic feet per minute. At this rate, how long will it take Frankie to completely fill the tank without it overflowing?
Accepted Solution
A:
the volume of the tank = [tex] \frac{4}{3} \pi r^{3} = \frac{4}{3} \pi (6)^{3}=288 \pi [/tex] ft^3
the time needed to fill the tank = 288pi / 23 = 39.3 minutes
