What type of volunteer work would be the most rewarding?

Explanation:

Prior knowledge is the knowledge that someone already has before they even meet any kind of new information. Someone's understanding of a text, for example, might be improved by using knowledge that he or she gathered before even reading the text.

Although some questions depend on learning new information to answer, knowing which work is most rewarding can be based only in prior knowledge. No new information is required to answer.

either a donut or a sphere or a pancake or a flat sphere. it depends on where the vertical line is.

if the line goes through the center of the circle and is perpendicular to a diameter containing the center, then you get a flat circle.

if the line and the diameter of a the circle meet in the center of the diameter and at an angle, you get a pancake.

if the line is on the circumference of the circle and is at right angles   to the circle you get a ring.

if the line contains the diameter, you get a sphere.

the the line is parallel to the diameter and touches the circumference, you get a donut.
