Final answer:
A quarter of a circle plus a tenth of a circle equals 35% of a circle.
Step-by-step explanation:
A quarter of a circle refers to a 90-degree arc, forming one-fourth of the entire circular shape. It spans from the center to a point on the circumference, creating a right angle. In trigonometry, this corresponds to a quarter of the unit circle's circumference.
In order to find the percent of a circle that is represented by a quarter of a circle plus a tenth of a circle, we need to add these two quantities together.
Since one quarter of a circle is 25% and one tenth of a circle is 10%, we add these percentages together:
= 25% + 10% = 35%.
Therefore, a quarter of a circle plus a tenth of a circle represents 35% of a circle.
