what is the volume (in cubic units) of a cylinder with a radius of 3 units and a height of 12 units? assume that pi = 3.14 and round your answer to the nearest tenth when necessary.
To find the volume of a cylinder, you can use the formula:
Volume = π * r^2 * h
Given that the radius (r) is 3 units and the height (h) is 12 units, substitute these values into the formula:
Volume = π * 3^2 * 12
Simplifying the equation gives:
Volume = π * 9 * 12
Volume = 108π
As π is approximately 3.14, you can substitute this value to calculate the volume:
Volume ≈ 3.14 * 108
Volume ≈ 339.12
Therefore, the volume of the cylinder is approximately 339.12 cubic units.
