what is the volume of a can that is 3 inches in radius and inches high?

pi*r^2*h
where h is the height (which isn't included in the problem).

To find the volume of a can, you need to use the formula for the volume of a cylinder, which is π * r^2 * h.

Given that the radius of the can is 3 inches, and the height is not provided, we cannot calculate the exact volume without the height value. If you have the height of the can, you can substitute it into the formula and solve for the volume.

For example, if the height of the can is 5 inches, you would have:
Volume = π * (3 inches)^2 * 5 inches
Volume = π * 9 square inches * 5 inches
Volume = π * 45 cubic inches

So, if you have the height of the can, you can substitute it into the formula to find the exact volume.
