A cylinder has a diameter of 8 inches in a height of 7 inches. What is its volume and cubic inches to the nearest tenths place
To find the volume of a cylinder, you use the formula V = πr^2h, where r is the radius of the cylinder and h is the height.
Given that the diameter is 8 inches, the radius is half of the diameter, so the radius (r) is 4 inches. The height (h) is 7 inches.
Plugging these values into the formula, we get:
V = π(4)^2(7)
V = π(16)(7)
V ≈ 352 cubic inches
Therefore, the volume of the cylinder is approximately 352 cubic inches.
