In Illustrator, What is the best way to re-create the white radiating stripes seen here (without eyeballing)? I have tried making a blend and using replace spine feature, but the shapes don't radiate, they stay vertically positioned. I also made a pattern brush but it won't allow the graduated size change. Any advice? thanks to all of you in advance.
Drop a horizontal and vertical guide, draw a circle with the guide intersection as the origin, and then draw an intersecting triangular segment which extends over the edge of the circle.
Select both circle and segment. Click on Window > Pathfinder, then hit Intersect
Use the Rotate tool, click on the segment, hold Alt while clicking to set the origin, and when the dialog opens set the desired angle. Click on the Copy button. Then CTRL+D repeatedly until the segments are rotated and copied all the way round in a circle.
Draw two intersecting circles, one centred on the origin, and one larger with the origin lower and the edge just going slightly over the bottom of the rotated segments.
Use the Shape Builder tool to join and create all the pieces. Select and delete those that are not required.
Another way of doing the "rays" part is by using a circle with a dashed, very thick outline:
