No. You want the volume of the sphere, not the area.
 
  • #3
ooooops

V of sphere = 4/3 pi r^3 where r = 1, V = 4/3 pi

so i got 4pi

Correct.
 

1. What is the Divergence Theorem problem?

The Divergence Theorem is a mathematical concept that relates the flow of a vector field through a closed surface to the divergence of the field within the surface. It is also known as Gauss's Theorem or Ostrogradsky's Theorem.

2. What is the purpose of the Divergence Theorem problem?

The Divergence Theorem is used to calculate the flow of a vector field through a closed surface in three-dimensional space. It is an important tool in studying fluid mechanics, electromagnetism, and other physical phenomena.

3. What are the prerequisites for solving a Divergence Theorem problem?

In order to solve a Divergence Theorem problem, one must have a solid understanding of vector calculus, including vector fields, line integrals, and surface integrals. Knowledge of multivariable calculus and differential equations may also be helpful.

4. What are the steps for solving a Divergence Theorem problem?

The steps for solving a Divergence Theorem problem typically involve identifying the vector field and the closed surface, calculating the divergence of the field, and setting up the integral for the flow through the surface. The integral can then be evaluated to find the solution.

5. What are some real-world applications of the Divergence Theorem problem?

The Divergence Theorem has many practical applications, including calculating the flow of air or water through a closed surface, analyzing the flow of electric or magnetic fields, and studying the behavior of fluid flow in pipes or channels.
