Proving surface area of sphere
WebbThe surface area of a sphere is the region covered by its outer surface. On the other hand, the volume represents the three-dimensional space occupied by the figure. We can calculate the surface area of a sphere using the formula A=4πr² and we can calculate its volume using the formula V= (4/3)πr³, where r is the radius of the sphere. WebbA parametric surface is a function with domain R2 and range R3. We typically use the variables u and v for the domain and x, y, and z for the range. We often use vector notation to exhibit parametric surfaces. Example 16.6.1. A sphere of …
