In three dimensions the formula for the volume of the ball enclosed within a sphere of radius R is (4/3)πR 3 and for the area of the sphere is 4πR 2. Note that the terminology is that a circle of radius R or a sphere of radius R apply to geometric figures whose points lie a distance of exactly R from their centers. We provide two approximate formulas for the upper tail probability of the distribution based on nonlinear renewal theory and an integral-geometric approach called the volume-of-tube method. This study is motivated by the detection problem of the interactive loci pairs which play an important role in forming biological species. The Greek mathematician Archimedes discovered that the surface area of a sphere is the same as the lateral surface area of a cylinder having the same radius as the sphere and a height the length of the diameter of the sphere. Theorem 1. The volume of a spherical cap is πh2(r− h 3) π h 2 (r - h 3),  when h h is its height and r r is the radius of the sphere.

Apply this law to the situation where the volume V is a sphere of radius r centered on a point-mass M. It's reasonable to expect the gravitational field from a point mass to be spherically symmetric. (We omit the proof for simplicity.) By making this assumption, g takes the following form: To find the potential of the ball, it is more convenient to first determine the potential of the sphere (using the surface integral) instead of calculating the triple integral, and then get the result for the ball (by performing one more integration). So, calculate the potential of the sphere of arbitrary radius $$r$$ $$\left( {r \le R} \right).$$
