Need to create a "pie slice" buffer somehow

[TatyanaDeryugina1]

I have a bunch of pollution monitor locations and need to calculate which counties lie within 100 miles AND within 0-30 degrees, 30-60 degrees, 60-90 degrees, etc, of each monitor. In other words, I need to draw a segmented circle around each monitor and then calculate which counties intersect each circle segment. I haven't been able to find anything that would let me do this. Any ideas?

I have not used this script myself but it seems like it will do what you need

Generate Polygons from Points, Azimuth and Radius

This is perfect, thank you! Works great.
