To solve this worksheet, students need to substitute the given values of volume and height in the formula V = πr^2h. For example, if the height of a cylinder is 5 units and the volume of the cylinder is 80π cubic units, then the formula V = πr^2h becomes 80π= πr^2(5). On further simplification, it becomes 80π= 5r^2π and after dividing both sides by 5π it becomes 16=r^2. Taking square root on both sides, ±4=r, but the radius cannot be negative. Therefore, the radius of the cylinder is 4 units.
