What ever spacing you decide on, 10 ft for instance, is to be measured at the outside radius.
I would measure the radius from the center point, multiply by pi, then divide by 2. That is the distance around the 90 degree arc. Then divide that distance by 3 or 4 or 5 to try to get close the the 8 to 10 ft distance.

Example for a 30 ft outside radius.
(30 X 3.1415) / 2 = 47.122 ft.
You can see that if you rounded that up to 50 ft it would be 5 sections at 10 ft
So divide 47.122 by 5 and get 9.42 ft.
That would be 9 ft – 5 inches.

Don’t forget, if you want 5 sections, you need 6 cuts.

the pie shaped pieces should be like this so if the circumference is 56 ft =672” divided by 6 sections each section at the outside should measure 112 inches.
and the inside is 36’ =432 ” divided by 6 sections 72”
i will draw that out on the ground ad see what it looks like.

I’m no expert but I’ve done a little concrete. It sure looks to me like a score in the center of that arc would be a good idea.

Looks like too many cuts, but I suppose that’s because your arcs are not drawn to scale.
Also, you have 6 sections (7 cuts) instead of 5, but I guess you rounded 56 up to 60.
If the layout looks too tight in full scale , round down the number of sections.

WHAT I THINK WE ARE GOING TO DO IS JUST 3 MAJOR SECTIONS WITH THE CALIFORNIA STYLE.USING THE CENTER EDGER AND SAW CUT THE IN BETWEEN SECTIONS.
