Use the ruler to measure the size of the circle you want - this will be a line all the way across the whole circle. Then, measure a piece of string with the ruler -- make this half the size of the original line.
Use a thumbtack to tack the string in the spot you want the middle of your circle. Use a bit of tape to tape the other end onto your pencil (don't wrap it around or you will end up with a smaller circle!) Gently move the pencil around the thumbtack to make your circle.

How do draw a circle with a compass?
To draw a circle with a compass, first set the distance between the point and the pencil of the compass using a ruler. This distance is the radius. Now, place the point on the paper where you want the center of the circle. Spin the compass around the point, lightly dragging the pencil on the paper, and you will have a circle.
How can you use a compass to draw a circle if you know its raduis or diameter?
If you know the radius place the compass point on a ruler and the pencil end the radius distance away from it. Then put the point on the paper and spin to draw the circle. If you know the diameter divide by two to get the radius and place the compass point on a ruler and the pencil end the radius distance away from it. Then put the point on the paper and spin to draw the circle.
How to make a circle by using only ruler and pencil?
