Write down an (in)equality which describes the solid ball of radius 66 centered at (10,−10,−7).(10,−10,−7). It should have a form like x2+y2+(z−2)2−4>=0x2+y2+(z−2)2−4& gt;=0, where you use one of the following symbols ≤,<,=,≥,>≤,<,=,≥,>.

Equation of solid ball is .

Step-by-step explanation:

A equation of a solid ball centered at (a,b,c) with radious r is of the form,

Here takes the inner region and outer surfaces of the solid. So in this problem center (a,b,c)=(10,-10,-7) and radious r=66, then equation of required solid ball is,

after simplifying it i got: -36.25 as my answer. hope that !
