Question

What is the distance between `(-6,3,-4)` and `(-9,10,2)`?

Answer 1

`sqrt(94)`

Explanation:

The distance formula between two points in 2D is `sqrt((x_1-x_0)^2+(y_1-y_0)^2`.

The distance formula between two points in 3D is similar: `sqrt((x_1-x_0)^2+(y_1-y_0)^2+(z_1-z_0)^2)`.

We just need to substitute the values in: `sqrt((x_1-x_0)^2+(y_1-y_0)^2+(z_1-z_0)^2)=sqrt((-9-(-6))^2+(10-3)^2+(2-(-4))^2)=sqrt(94)`.
