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?

Find the area of the circle than multiply it by the height to get your answer.

Um...What's the answer tho?

To find the amount of water needed to fill the tank, we need to calculate the volume of the cylindrical tank.

The volume of a cylinder can be calculated using the formula:

Volume = π * r² * h

Where π is a mathematical constant (approximately equal to 3.14159), r is the radius of the cylinder, and h is the height of the cylinder.

To find the radius, we need to divide the diameter (20 feet) by 2. So, the radius is 20 feet / 2 = 10 feet.

Plugging in the values into the formula, we have:

Volume = π * 10² * 15

Calculating this, we get:

Volume ≈ 3.14159 * 10 * 10 * 15 ≈ 4712.39 cubic feet

Therefore, approximately 4712.39 cubic feet of water is needed to fill the tank.
