SUMMARY
The volume of a cylinder is calculated using the formula V = πr²h. In the discussion, two cylinders are compared: one with a radius of 2 and height of 10, and another with a radius of 1 and height of 20. The calculations show that the first cylinder has a volume of 40π, while the second also calculates to 40π, indicating they are equal in volume. However, the confusion arose from misapplying the formula, specifically using 2r instead of r in the calculation.
