Calculating Volume of Cylinders

The video tutorial by Amel Kumar demonstrates how to find the radius of a cylindrical can given its height and volume. The problem involves converting units, applying the formula for the volume of a cylinder, and isolating the radius. The calculation is performed using a calculator, and the result is rounded to the nearest millimeter. The final answer is presented as the radius in millimeters.
