Write down an (in)equality which describes the solid ball of radius 2 centered at (-2, 5, 2). It should have a form like ????2 ?

$\text{We know that the euation of the sphere with radius r and centered at (h,k,l)}\\
\text{is given by:}\\
\\
(x-h)^2+(y-k)^2+(z-l)^2=r^2\\
\\
\text{here we have given a solid ball of radius 2 centered at }(-2, 5,2), \text{ so the }\\
\text{region of the ball will be all the area within the ball.}\\
\text{Hence the inequality that will describe the ball is give given by}$

$(x-(-2))^2+(y-5)^2+(z-2)^2\leq 2^2\\
\\
\Rightarrow (x+2)^2+(y-5)^2+(z-2)^2\leq 4\\
\\
\text{hence the required inequality that describes the ball is:}\\
\\
(x+2)^2+(y-5)^2+(z-2)^2-4\leq 0$
