45 degrees, if the wedges are equal.
A central angle is formed by two radii in a circle that extend from the center to the circumference, creating an angle at the center. The vertex of the angle is located at the center of the circle, and the two sides of the angle intersect the circle at different points. The measure of the central angle is defined by the arc it subtends on the circle's circumference. Visually, it appears as a wedge shape within the circle.
There are various ways of measuring circles, since a circle has a radius, a diameter, and a circumference, so your question asking how to divide a circle to 15 cm is not as precisely stated as it might be. You can use a segment of a circumference to get 15 cm, by taking the appropriate wedge out of the circle, but even then, unless we know what the radius of the circle is, we cannot tell you what angle is needed to obtain the wedge you want, with a 15 cm circumference.
In a regular octagon, the circle circumscribing it has eight equal arcs, as the octagon has eight sides. The total measure of a circle is 360 degrees, so each arc measures 360 degrees divided by 8. Therefore, each arc in a circle circumscribed by a regular octagon measures 45 degrees.
If you measure the middle of the circle and then times it by 3
the amount of space inside a circle
A wedge shaped portion of a circle is called a sector.
sliver
A sector is a wedge of a circle.
64°/360° = 8/45 of the circle = 0.1777 (rounded, repeating)The arc's length is 8/45 of the circle's total circumference.
360/8 = 45 degrees

A wedge, or rather, a combination of an infinite number of wedges arranged in a circle.
Easiest way is to draw a pie chart. There are 360° in a circle, so to represent 2/3 you need to fill in a 240° wedge in the chart. A line from the center of the circle to the top quadrant would be one side of the wedge. A line from the center of the circle angled 30° off from the bottom quadrant would be the other side of the wedge.
Wedge? IDK. Like sector-a part of a circle containing the circle's center and an ark.
The measure from the center of a circle to its edge is the radius.
