Question

A water tower is used to store fire fighting water at an industrial plant. The tank on top of the tower is in the shape of a cylinder wit a height of 15 feet and a diameter of 7 feet. One cubic foot is approximately 7.5 gallons. How many gallons of water are in the tank if it's 55% full?

Answer 1

V=hπr^2

(15π(3.5^2)ft^3)(55/100)(7.5gal/ft^3)≈2381.23 gal  (to nearest hundredth of a gallon)
