Powerpoint Slide with a pie chart

This is a small job. Actually decided now I need around 8 slides doing but the major one is the one following. I am doing a webinar shortly and would like to use ONE slide that has a pie chart on it showing the following statistics.

3% - Ideal and have a need
7% - Open but not actively looking now.
30% - Aware of your service
30% - Totally unconscious
30% - NO!


I need this on pie chart so I can add it to some more slides I use later, haven't done those yet. But have no idea how to do a pie chart on a PPT slide. I would like this done and put on a slide that I can edit.

Thank you
Audrey
