To solve this worksheet, students need to identify the radius and height from the given figure and then substitute those values in the formula V = ⅓ πr^2h. For example, if the radius of a cone is 4 units and the height of the cone is 5 units, then the formula V = ⅓ πr^2h becomes V= ⅓ π(4)^2(5). After simplifications, the final values can be V= 80/3 π cubic units or V ≈ 83.78 cubic units.
