Answer:
Distance between points R=(9,7,8) and origin is,
d = 13.9283 units.
Step-by-step explanation:
We have to calculate the distance between the two points,
Where,
the first point is origin, i.e.
Q = (0,0,0)
and R = (9,7,8)
According to distance formula, the distance between two points can be given by

= 13.9283
Hence, the distance between two points R=(9,7,8) and origin is 13.9283 units.
