circle remainders

a square has had  touching
circles,
semicircles,
quadrantsdrawn inside them








which has the largest fraction (ratio) of orange to the whole square?

intended to be practice in calculating areas of circles and bits of circles but
several of the designs can be viewed as a scaling up, or down, of a part of another diagram

from an article by DP Eperson [in Mathematics in School, January 1992]
