  1. Welcome Geometry our Lesson

  2. SPHERE  Today we are going to learn about sphere. Lets take a look at what sphere is. A sphere (from Greek  sphaira, "globe, ball" is a perfectly round geometrical object in three-dimensional space, such as the shape of a round ball

  3. STEPS Let see the formula of sphere: 1-Use this equation: V = ⁴⁄₃πr³. The "V" stands for volume and "r" stands for radius of the sphere. 2-Find the radius. Sometimes, you'll be given the radius; other times you may be given the diameter. If you have the diameter, simply divide it by two (or half it). You might also be given the surface area or some other property. Don't freak, just find the formula for that property, set it equal to the value you know is the property, and find the radius from there by solving the equation. 3-Cube the radius. This is multiplying the radius by itself three times, (Radius*Radius*Radius). Note that multiplying any value by itself three times is called cubing it.

  4. Lets watch a video about formula of Sphere

  5. Lets discover more about the sphere How to Turn a Sphere Inside Out
