A cylindrical tank has a radius of 15 ft. and a height of 45 ft. How many cubic feet of water can the tank hold?

V = pi * r^2 * h

V = 3.14 * 15^2 * 45

V = 3.14 * 225 * 45

V = 31,792.5 cu. ft.

To find the volume of the cylindrical tank, we can use the formula:

Volume = π * r^2 * h

where:
π is a mathematical constant approximately equal to 3.14
r is the radius of the tank
h is the height of the tank

Given:
Radius (r) = 15 ft
Height (h) = 45 ft

Using the formula, we can calculate the volume:

Volume = π * 15^2 * 45

Volume = 3.14 * 225 * 45

Volume = 3.14 * 10125

Volume ≈ 31807.5 cubic feet

Therefore, the cylindrical tank can hold approximately 31,807.5 cubic feet of water.

To find the volume of the cylindrical tank, we can use the formula for the volume of a cylinder: V = πr^2h, where V is the volume, r is the radius, and h is the height.

In this case, the radius is given as 15 ft and the height is given as 45 ft. Plugging in these values into the formula, we get:

V = π(15 ft)^2(45 ft)
V = 3.14 * 15 ft * 15 ft * 45 ft

Calculating further:

V ≈ 3.14 * 225 ft^2 * 45 ft
V ≈ 3.14 * 10,125 ft^3
V ≈ 31,798.5 ft^3

Therefore, the cylindrical tank can hold approximately 31,798.5 cubic feet of water.
