A quarter of a circle plus an eighth of a circle is what percent of a circle
To find the total percentage of a circle, we add the percentages of each part.
A quarter of a circle is 25% of a circle, and an eighth of a circle is 12.5% of a circle.
Thus, a quarter of a circle plus an eighth of a circle is 25% + 12.5% = 37.5% of a circle.
