Use the 3-d version of the distance formula
| 2 2 d = ( x 2 - x 1 ) 2 + ( y 2 - y 1 ) 2 + ( z 2 - z 1 ) 2 2 2 | ̲ ¯
where ( x 1 , y 1 , z 1 ) , ( x 2 , y 2 , z 2 ) are 2 coordinate points
the 2 points here are ( 3 , - 1 , 1 ) and ( 1 , - 2 , 0 )
let ( x 1 , y 1 , z 1 ) = ( 3 , - 1 , 1 ) , ( x 2 , y 2 , z 2 ) = ( 1 , - 2 , 0 )
d = ( 1 - 3 ) 2 + ( - 2 + 1 ) 2 + ( 0 - 1 ) 2
d = 6 2.45 to 2 dec. places
