How to break a circle into separate sectors when working with a map and the 2GIS API?

Question

Canvas

I am developing a web application using a 2GIS map. There was a need to draw a circle on the map with a division into separate sectors. In general, when working with Canvas , you can repeatedly use the arc (...) method and, by setting different angles, create sectors.
Does anyone have any idea how to solve this problem in the context of a geographic map?
