Acylindrical cattle watering tank is 14 feet in diameter and 3.5 feet tall. about how many cubic feet of water is needed to fill the tank 75% full

Formula

Volume = πr²h


Find Radius

Radius = Diameter ÷ 2
Radius = 14 ÷ 2
Radius = 7 feet


Find Capacity

Capacity = πr²h
Capacity = π x (7)² x 3.5
Capacity = 538.78 ft³


Find 75% of Capacity

75% of 538.78 ft³
= 0.75 x 538.78 
= 404.09 ft³ (nearest hundredth)


404.09 ft³
