A cylindrical 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

Respuesta :

----------------------------------------
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)
