Question

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?

Answer 1

Volume of the sphere = 4/3 πr³

Volume of the sphere = 4/3 π (6)³

Volume of the sphere = 904.78 ft³ (nearest hundredth)

1 minute = 23 ft³

Find number of minutes :
904.78 ÷ 23 = 40 mins (nearest minutes)
