In this project, we find formulas for the enclosed by a hypersphere in n?dimensional spaces
1 Use a double integral, and trigonometric substitution, together with Formula 64 in the Table of Integrals, to find the area of a circle with radius r
2 Use a triple integral and trigonometric substitution to find the volume of a sphere with radius r.
3 Use a quadruple integral to find the hypervolume enclosed by the hypersphere.....
(Use only trigonometric substitution and the reduction formulas for....
4 Use an n-tuple integral to find, the volume enclosed by a hypersphere of radius r in
n-dimensionai space R [Hint: The formulas for n even and for n odd are different.]
The volume of a hypersphere is found in this well presented solution.
