A cylindrical water tank has a diameter of 20 feet and a height of 15 feet. How much water is needed to fill the tank?

Recall the formula V = pi r squared h.
300Pi cubic feet
1,500Pi cubic feet
2,250Pi cubic feet
6,000Pi cubic feet

1500 cubic feet water is needed to fill the tank. Option B.

Step-by-step explanation:

Given,

The diameter of the cylindrical water tank is 20 ft.

So, the radius (r) = 10 ft

Height (h) = 15 ft

To find the water to be filled in the tank we need to find out the volume.

Formula

volume of cylinder (V) = πr²h

Now,

Putting the values of r and h in the given formula we get,

V = π×10²×15 = 1500π cubic feet

Hence,

1500 cubic feet water is needed to fill the tank.
