To find the volume of a cylindrical can, you can use the formula: ( V = \pi r^2 h ), where ( r ) is the radius and ( h ) is the height. Given that the diameter is 8 cm, the radius ( r ) would be 4 cm. With a height of 12 cm, the volume is ( V = \pi (4^2)(12) = \pi (16)(12) = 192\pi ) cubic centimeters, which is approximately 602.88 cm³.
