the answer is 1500. Even if u do multiply it by pi the answer isnt one of the options.
The volume of the cylindrical water tank is 1500π ft³ OR 4712.39 ft³
From the question, we are to determine how much water is needed to fill the tank. That is, the volume of the tank.
To calculate the volume of the tank, we will use the formula for calculating the volume of a cylinder
The volume of a cylinder can be calculated by using the formula,
V= πr²h
Where V is the volume
r is the radius
and h is the height
From the given information,
Diameter (d) = 20 feet
Radius (r) = Diameter / 2
∴ r = 20 feet / 2
r = 10 feet
and
h = 15 feet
Putting the parameters into the formula, we get
V = π × 10² × 15
V = π × 100 × 15
V = 1500π ft³ OR 4712.39 ft³
Hence, the volume of the cylindrical water tank is 1500π ft³ OR 4712.39 ft³
