The standard form of a sphere equation is:

$$$(x-h)^2+(y-k)^2+(z-m)^2=r^2$$$

where
$$r$$
is the sphere’s radius, and
$$h,k,\&\: m$$
are the respective
$$x,y,z$$
coordinates that define the sphere’s center point.

The standard form of a circle equation is:

$$$(x-h)^2+(y-k)^2=r^2$$$

where
$$r$$
is the circle’s radius, and
$$h\:\&\:k$$
are the respective
$$x\:\&\:y$$
coordinates that define the circle’s center point.

If a circle were centered at the origin
$$(h=0\:\&\:k=0)$$
, then the general form is:

$$$x^2+y^2=r^2$$$
