Question

Equation of a sphere with centre origin and radius r *​

Answer 1

Answer:

It turns out that the equation of a sphere with center (a,b,c) and radius r has the equation (x−a)2+(y−b)2+(z−c)2=r2. This formula has its origins in the general distance formula, which lets you calculate the distance between any two specific points, even in 3D space.
