Eight of them.
It equals 80%
To divide a circle into thirteenths, divide it into thirteen equal portions, or pieces.
Only once, there will only be eights parts however you divide it.
0.66 is approximately 2/31/8 = 0.125You can fit 0.66/0.125 = 5 eights in 0.66, but you're left with 7/200 which is too small to divide in eights.
Construct a circle with a 4.5 radius. The circle's circumference is 360 degrees. So mark out 3 by 120 degrees on the circumference and join them to the centre of the circle which will divide the circle into three equal parts.
From the center of the circle, draw like a cross from there.
1.75 eights is equal to 14.
circle is 2d so, just fold it 15!
Not everyone knows ?
A circle has 360 degrees. Divide 360 by 18 and you will find that each equal part of the divided circle is 20 degrees.
Starting at one point of the circle, draw a straight line through the center of the circle to the other side. This line is called a diameter. It will divide the circle into 2 equal pieces.Now, if you want to divide the circle into any number N of equal pieces, follow these steps in orderdivide the diameter into N equal segments,from one endpoint of the diameter, draw half circles towards every endpoint of the equal segments,flip the circle,from the other endpoint of the diameter, draw again half circles towards every endpoint of the equal segment (but now filling the other side of the circle).The resulting parts of the circle have equal area.
