Question

What is the distance between `(3,13,10)` and `(3,-17,-1)`?

Answer 1

Distance between `(3,13,10)` and `(3,-17,-1)` is `31.95` units.

Explanation:

Distance between two points `(x_1,y_1,z_1)` and `(x_2,y_2,z_2)` is given by `sqrt((x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2)`.

Hence distance between `(3,13,10)` and `(3,-17,-1)` is

`sqrt((3-3)^2+((-17)-13)^2+((-1)-10)^2)=sqrt((0)^2+(-17-13)^2+(-1-10)^2)`

= `sqrt((0)^2+(-30)^2+(-11)^2)=sqrt(0+900+121)`

= `sqrt1021=31.95`
