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?
Volume of the sphere = 904.78 ft³ (nearest hundredth)
1 minute = 23 ft³
Find number of minutes : 904.78 ÷ 23 = 40 mins (nearest minutes)
------------------------------------------------------------------------------------ Answer: It takes about 40 minutes to completely fill the tank. ------------------------------------------------------------------------------------
