circle and spherical: center, area of circle from eqn of two

[Apprentice123]

Two questions about circles and spherical

1) How can I calculate the radius, the center and area of a circle formed by the equation of two spheres?

2) How do I check if a point is on inside, outside or on the spherical surface?

THANKS

This link may help. I assume you mean the area of the circle formed by the intersection of two sphere.

You can also find the volume of the region formed by the spheres intersection.
