Finding the Volume of a Sphere

The video tutorial explains how to find the volume of a sphere by comparing it to the volume of a cylinder. It begins with a review of calculating the volume of a cylinder, using the formula base times height. The tutorial then introduces the concept of a sphere and explains how its volume is derived by comparing it to a cylinder with the same radius and height. By breaking the sphere into hemispheres and using water to demonstrate, it shows that the volume of a sphere is 2/3 of the volume of a cylinder. The formula for the volume of a sphere is derived as 4/3 times pi r cubed. The tutorial concludes with an example problem involving a snow globe to apply the formula.
