Finish the following sentence with the best choice: how do you find the volume of a cylinder

Choices:
- Calculate the area of the base (which is a circle) by using the equation πr² where r is the radius of the circle. Then, multiply the area of the base by the height of the cylinder by the base again to find the volume.
- Calculate the area of the base (which is a circle) by using the equation πr² where r is the radius of the circle. Then, multiply the area of the base by the height of the cylinder to find the volume.

Answer:
