The formula for the distance for 3-dimensional coordinates is similar or 2-dimensional; it is: d = ( x 2 - x 1 ) 2 + ( y 2 - y 1 ) 2 + ( z 2 - z 1 ) 2
We have the two coordinates, so we can plug in the values for x, y, and z:
d = ( - 1 - ( - 5 ) ) 2 + ( - 4 - 3 ) 2 + ( 1 - 9 ) 2
Now we simplify:
d = ( 4 ) 2 + ( - 7 ) 2 + ( - 8 ) 2
d = 16 + 49 + 64
d = 129
If you want to leave it in exact form, you can leave the distance as 129 . However, if you want the decimal answer, here it is rounded to the nearest thousandth's place:
d 11.358
