The equation of a sphere with radius \(R\) and center \((i, j, k) \) is

\[ (x-i)^2+(y-j)^2+(z-k)^2=R^2.\]

Example Question 1

---

This is the answer to the question, with a detailed solution. If math is needed, it can be done inline: \( x^2 = 144 \), or it can be in a centered display:

\[ \frac{x^2}{x+3} = 4y \]

And our final answer is 10. \( _\square \)
