Can you interact with the points extracted from a cloud?

You extract the points from a cloud.
I know you can report the locations of the individual points, but can you use that individual point data?

Example:

You extract cloud points that make up an arc.
You want to calculate the distance between a measured center circle and each one of those points. A radius through each point of the cloud.
Is this possible?
