  1. Feb 18,  · In simple terms, a sphere is a solid round ball. To calculate the mass of a sphere, you must know the size (volume) of the sphere and its density. You might calculate volume using the sphere’s radius, circumference or diameter. You can also submerge the sphere in water to find its volume by displacement%(32).

  2. That's right, the solution is agnostic of the diameter of the sphere. We could have a sphere as large as a planet, bore a hole 6" in length through it (it would be a pretty wide hole!), and the volume of the earth left in the ring around the edge would be 36π cubic inches. This is a very neat answer, and you can see why Mr Gardner liked it so.

  3. A sphere that has the Cartesian equation x 2 + y 2 + z 2 = c 2 has the simple equation r = c in spherical coordinates. Two important partial differential equations that arise in many physical problems, Laplace's equation and the Helmholtz equation, allow a separation of variables in spherical coordinates.

  4. Spheres aren’t three-dimensional—they are two-dimensional. This is evident from the fact that in order to specify a point on a sphere, you only need two pieces of information, such as latitude and longitude. If you include the interior of the sphe.

  7. The Circumference of a circle or a sphere is equal to times the Diameter. $\text"Circumference" = ⋅ \text"Diameter"$ $C = π ⋅ D$ Figure #4., The circumference is .

  8. Volume of a sphere formula. The volume of a sphere is 4/3 x π x (diameter / 2) 3, where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is 4/3 x π x radius barcountfitmaduseshoyracalromarda.coinfo on the figure below: Since in most practical situations you know the diameter (via measurement or from a plan/schematic), the first formula is usually most useful, but it's easy to do it both ways.
