To divide a circle into thirteenths, divide it into thirteen equal portions, or pieces.

circle is 2d so, just fold it 15!
You divide 360 degrees by eight (there are 360 degrees in a circle) so each section would be 45 degrees.
A radius squared fits pi times into a circle (The area of a circle divided by pi is the radius squared).
Infinite amount of times. Its just a matter of how accurate you can draw the dividing lines.
To calculate the radius of a circle by using the circumference, take the circumference of the circle and divide it by 2 times π. For a circle with a circumference of 15, you would divide 15 by 2 times 3.14 and round the decimal point to your answer of approximately 2.39
In order to convert the area of a circle to the circumference of the circle, divide by the radius and multiply by two. The formula for the circumference of a circle is pi times the diameter.
multiply pi times diameter and divide by 2!

Eight of them.
Divide the diameter by 2 to get the radius. Then use the standard formula for the area of the circle (which is pi times radius squared).
As many times as you want.
Circumference = Pi * DiameterThe 3.14 is an approximation for Pi. So if you are finding the diameter of a circle, then divide the cirumference by 3.14.
The Perimeter of a circle is it's circumference. And the circumference is the diameter times pi. So to find the area, divide the circumference by pi, and get the diameter. Then divide the diameter by 2, to get the radius. Then multiply the radius times itself, and multiply that by pi.
Divide by pi then divide by 2 then square the number and then multiply by pi
