The distance between (2,15,7) and (2,4,−4) is 15.5562

Explanation:

In a two dimensional plane, distance between two points (x1,y1) and (x2,y2) is given by

√(x2−x1)2+(y2−y1)2

and in three dimensional space, distance between two points (x1,y1,z1) and (x2,y2,z2) is given by

√(x2−x1)2+(y2−y1)2+(z2−z1)2

Hence, the distance between (2,15,7) and (2,4,−4) is

√(2−2)2+(4−15)2+(−4−7)2

= √02+(−11)2+(−11)2=√0+121+121=11√2=15.5562
