Finding area between sphere and parabloid

In summary, the formula for finding the area between a sphere and a parabloid is given by the double integral of the function representing the parabloid over the region bounded by the sphere. The bounds for the double integral can be determined by setting the equations for the sphere and parabloid equal to each other and solving for the variables. Any coordinate system can be used, but the most commonly used are Cartesian, cylindrical, and spherical coordinates. The radius of the sphere and the coefficient of the parabloid's equation both affect the area between them, with a larger radius or smaller coefficient resulting in a larger area and vice versa. This concept has practical applications in engineering, physics, and architecture, such as calculating surface area and volume.

Homework Statement


Find the volume above the sphere x^2+y^2+z^2 = 6 and below the parabloid z = 4-x^2-y^2.



Homework Equations





The Attempt at a Solution


I did a triple integral in cylindrical coordinates
Triple Integral: dzdrdθ
where z is between (6-r^2)^(1/2) to (4-r^2) and dr goes from 0 to 2^(1/2) and dθ goes from 0 to 2θ. Are these the proper parameters?

Assuming you meant r, not dr, θ, not dθ, and 2π, not 2θ, yes.
 

Related to Finding area between sphere and parabloid

1. What is the formula for finding the area between a sphere and a parabloid?

The formula for finding the area between a sphere and a parabloid is given by the double integral of the function representing the parabloid over the region bounded by the sphere. This can be represented as A = ∬f(x,y)dA.

2. How do we determine the bounds for the double integral when finding the area between a sphere and a parabloid?

The bounds for the double integral depend on the shape and orientation of the sphere and parabloid. In most cases, the bounds can be determined by setting the equations for the sphere and parabloid equal to each other and solving for the variables.

3. Can we use any coordinate system when finding the area between a sphere and a parabloid?

Yes, the coordinate system used may vary based on the problem at hand. However, the most commonly used coordinate systems are Cartesian, cylindrical, and spherical coordinates.

4. How does the radius of the sphere and the coefficient of the parabloid's equation affect the area between them?

The radius of the sphere and the coefficient of the parabloid's equation both affect the shape and size of the region between them. A larger radius or a smaller coefficient will result in a larger area, while a smaller radius or a larger coefficient will result in a smaller area.

5. What are some real-life applications of finding the area between a sphere and a parabloid?

Finding the area between a sphere and a parabloid has many practical applications in fields such as engineering, physics, and architecture. For example, it can be used to calculate the surface area of a dome-shaped structure or to determine the volume of a curved container.
