The distance formula for 3 dimensions is:

$\sqrt{{(\Delta x)}^{2}+{(\Delta y)}^{2}+{(\Delta z)}^{2}}$

In this case,

$\Delta x=8-9=-1$

$\Delta y=6-2=4$

$\Delta z=2-0=2$

So the distance is:

$\sqrt{{(-1)}^{2}+{4}^{2}+{2}^{2}}=\sqrt{1+16+4}=\sqrt{21}$

$\sqrt{{(\Delta x)}^{2}+{(\Delta y)}^{2}+{(\Delta z)}^{2}}$

In this case,

$\Delta x=8-9=-1$

$\Delta y=6-2=4$

$\Delta z=2-0=2$

So the distance is:

$\sqrt{{(-1)}^{2}+{4}^{2}+{2}^{2}}=\sqrt{1+16+4}=\sqrt{21}$
