What is the area of the cross section of a sphere that is 12 units from the center of the sphere?
That depends on how many units there are in the diameter of the sphere. * * * * * If the radius of the sphere is R units then the radius of the cross section is sqrt(R2 - 122) Therefore the cross sectional area is pi*(R2 - 122) square units.
What is the area of the cross section of a sphere that is 3 units from the center of the sphere?
The cross section at this point forms a circle and its area is pi/32 which equals 9*pi square units. * * * * * Not quite. If the radius of the sphere is R units then the radius of the cross section is sqrt(R2 - 32) Therefore the cross sectional area is pi*(R2 - 32) square units.
What degree in cross section of a sphere?
Every cross-section of a sphere is a circle.
How do you calculate the cross section area of a sphere?
If I am correctly understanding the question. You are simply looking for the area of a circle or pi * R^2 or pi/4 * D^2. ------------------------------------ The formula above is correct for the planar cross section area through the center of the sphere, where the constant pi = 3.14159.... and R is the radius of the sphere, and D is the diameter. If the plane you are interested in does not go through the center of the sphere, it is not correct. To get the area though a plane that does not go through the center, you need to know the offset distance of the plane from the center of the sphere. Calling this distance d, the area is A = pi * (R^2 - d^2) [Positive values only. If the answer comes out negative, the offset distance is greater than the radius of the sphere, so the plane does not intersect the sphere] This can be derrived from a simple 2-D diagram.
