The video tutorial explains how to calculate the volume of a sphere using the formula 4/3 * π * radius cubed. It demonstrates the process with a sphere of radius 3 inches, simplifying the expression to find the volume in terms of Pi and then approximating it using 3.14 for Pi. The tutorial concludes with a recap of the formula.

What formula is used to calculate the volume of a sphere?

• Volume = 2/3 * Pi * radius squared

• Volume = 4/3 * Pi * radius cubed

• Volume = Pi * radius squared * height

• Volume = 1/3 * Pi * radius squared * height
