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.

false.

step-by-step explanation:

false.

cavalieri's principle makes that statement about the volumes, not about the areas.

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
