To find the volume of a cylinder, you can use the formula V = πr^2h, where V is the volume, π is approximately 3.14, r is the radius, and h is the height.

For this cylinder with a radius of 8 inches and a height of 3 inches, we can substitute those values into the formula:
V = 3.14 * (8^2) * 3
V ≈ 602.88 in^3

Therefore, the volume of the cylinder is approximately 602.9 cubic inches.

To find the surface area of a cylinder, you can use the formula A = 2πrh + 2πr^2, where A is the surface area.

Substituting the values into the formula:
A = 2 * 3.14 * 8 * 3 + 2 * 3.14 * (8^2)
A ≈ 603.84 in^2

Therefore, the surface area of the cylinder is approximately 603.8 square inches.
