  • Volume of a Sphere.

  • Game.

  • Sphere is a perfectly round three-dimensional object.

  • To find the volume of a sphere, divide the sphere into equal sized pyramids with same base and height.

  • Fix me, please.

  • This is a pyramid.

  • Area of Base.

  • Height.

  • Volume of a pyramid is equal to 1 upon 3 into Area of base into Height.

  • Vertex of a pyramid.

  • Center of sphere.

  • Vertex of each pyramid coincides with the center of sphere.

  • Height of each pyramid is equal to the radius of the sphere.

  • Volume of the first pyramid is equal to 1 upon 3 into A1 into r.

  • Volume of the second pyramid is equal to 1 upon 3 into A2 into r.

  • Volume of the last pyramid is equal to 1 upon 3 into An into r.

  • Volume of sphere is equal to Total volume of all pyramids.

  • Base area of 1 Pyramid.

  • Base area of all Pyramids.

  • Base area of all Pyramids is equal to Surface area of sphere is equal to 4 into Pi into r square.

  • Volume of sphere is equal to 4 upon 3 into Pi into r cube.
