Find the volume of the figure below.
kiruha [24]

Hello!

To find the volume of a cylinder, use the formula: V = πr²h.

In the formula, r is the radius, and h is height of the figure.

In the given figure, the height of the cylinder is 8 feet and the radius is 5 feet. With those values, we can find the volume of the given figure.

V = π(5)²(8)

V = π(25)(8)

V = 200π, 628.32 (multiplied by π), 628 (multiplied by 3.14)

Therefore, the volume of this cylinder is 628.32 feet cubed.
