A circle divides a plane into three parts.
draw a + inside it, touching the outside of the circle-cut it into Quaters.
You can
Technically no because 360/7 is a repeating decimal but it can be approximated
The three parts are:the interior of the circle, the points on the circle (points on its circumference) the outside of the circle.
Only the diameter can divide the circle in to two equal parts.
Go to a pizzeria and get them to do it for you.
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.

By circling the diameter to 1300 cm and then cutting them in half and again to divide the equamatric. Its all in the way you look at it. Its REALLY simple.
A circular sector is formed by two radii and an arc. And the angle formed due to the two radii is central angle(Θ). Area of a sector = (Θ/360) πr2.If we divide a circle into seven sectors having equal central angles then the circle is divided into seven equal parts.Angle of the whole circle is 360o. So we should divide the whole angle into 7 equal parts each measuring 360o/7 and then forming the corresponding sectors.
