Calculating the Volume of a Sphere

This video tutorial from Moomoomath and Science explains how to calculate the volume of a sphere. It begins with examples of spheres, such as Earth and a basketball, and introduces the formula for volume: 4/3 times pi times the radius cubed. The video then provides two examples: one using a sphere's radius and another using its diameter, demonstrating how to apply the formula in each case. The tutorial concludes with a reminder to use the formula and a call to subscribe for more math and science videos.

What are some common examples of spheres mentioned in the video?

• Sun, Star, Galaxy

• Cube, Sphere, Cone

• Apple, Orange, Ball

• Basketball, Earth, Moon
