The number of degrees in one complete revolution of a radius is 360°.
Therefore the number of degrees covered in 1/5 of a revolution is 72° .
To divide a circle into 5 equal parts create 5 sectors each measuring 72° at the centre of the circle.
Select any one side and divide its length into 5 equal parts. Draw lines that are parallel to the adjacent side to the opposite side. This will divide the rectangle into 5 equal strips.
AnswerThere are 2pi radians in a full circle. If we cut a circle into 5 equal parts, each central angle will have 2pi/5 (or 72 degrees), and each arc intercepted form those central angles will be (2/5)(pi)(r). AnswerYes, you can, using just a compass and straight edge. For any given circle you construct, construct a pentagon inside it using that compass and straight edge, then use the vertices of the pentagon to divide the circle into 5 equal sectors. Use the link below to see how the construction proceeds.
Divide the square into five strips.
Divide the longer edge (or shorter one, for that matter) by 5, mark the 4 spots along the edge going by the answer of your division, and there you have it.
Since the circumference is equal to the diameter times pi, you need to divide the circumference by pi in this case.

Divide 3 inches in 5 equal parts
You divide it into parts of 1.2by4
Select any one side and divide its length into 5 equal parts. Draw lines that are parallel to the adjacent side to the opposite side. This will divide the rectangle into 5 equal strips.
12.5 ÷ 5 = 2.5
unknown
Try 105/5 = 21
Draw the pentagon on the outside of the circle with all five sides touching the circle. Now by dividing the pentagon into 5 equal segments to the center, the circle is divided as well into 5 equal segments. Mathmatically speaking, see the related link for more information
Select any one side. Divide its length into 5 equal parts. Do the same to the opposite side. Join the corresponding divisions. You will then have 5 equal rectangular divisions of the square.
5 out of 18 parts is 5/18. Multiply that by 360, since that's the number of degrees in a full circle.
5*20 cm = 1 meter
