Question

A triangle has corners at `(5 ,3 )`, `(9 ,2 )`, and `(6 ,7 )`. How far is the triangle's centroid from the origin?

Answer 1

`sqrt 544 /3`

Explanation:

The coordinates of the centroid would be `((5+9+6)/3, (3+2+7)/3)` or `(20/3 , 4)`

Distance from the origin would be `sqrt((20/3)^2 +4^2)= sqrt(544/9)= sqrt 544/3`
