WebNov 7, 2024 · The volume of a sphere is the radius cubed (times itself twice), times π, times 4/3. A = 4πr 2. The surface area of a sphere is the radius squared (times itself), times π, times 4. Since the area of a circle is πr 2, it can also be said that the surface area of a sphere is four times the area of the circle formed by its circumference. When the intersection of a sphere and a plane is not empty or a single point, it is a circle. This can be seen as follows: Let S be a sphere with center O, P a plane which intersects S. Draw OE perpendicular to P and meeting P at E. Let A and B be any two different points in the intersection. Then AOE and BOE are right … See more A circle of a sphere is a circle that lies on a sphere. Such a circle can be formed as the intersection of a sphere and a plane, or of two spheres.
