Answer:
32901 gallons
Step-by-step explanation:
First, we find the volume of the cylindrical water tank when it is full.
The volume of a cylinder is given as:
V =
where r = radius and h = height of the cylinder
The diameter of the tank is 20 feet, hence, its radius is 10 feet.
Volume, V, is therefore:
V =
This is the volume of the tank, when it is full.
When it is 70% full, the volume will be:
1 cubic foot () is 7.48 gallons.
Therefore, the volume of the 70% full tank in gallons will be:
4398.23 * 7.48 = 32901.05 gallons ≅ 32901 gallons
The tank contains 32901 gallons of water.
Answer:
approximately 32,900 gallons
Step-by-step explanation:
volume water in tank
v = πr²h * .70
v = π * 10² * 20 * .70
v = 4,398.2297150257 ft³
1 ft³ = 7.48 gallons
gallons in tank
4,398.2297150257 * 7.48 = 32,898.7582683922
~ 32,900 gallons
