Ans: 16 pieces
One chord divides the circle into 2 parts. Two chords divide the circle into 4 parts, in the third three chords divide the circle into 3 parts and the forth diagram 4 chords divide the circle into 11 parts.
Here you see that the first cut creates 1 new region (1+1)
The second cut creates 2 new regions (2+2)
The third cut creates 3 new regions (4+3) and the 4th cut creates 4 new regions (7+4)
So, 5th cut is (11+5)
This is mathematically represented as
F (n) = n + f (n-1)

What is the measure of the angle by the straight sides of the circle divided into 5 equal parts?
A circle has no straight sides but if you mean a circle that has been divided into 5 equal sectors then the angle of each sector is 72 degrees subtended by each arc of the circle.
What 2D shape looks like a squashed circle and no straight edges?
an ellipse, one of the four types of "conic sections": ellipse, circle, parabola, and hyperbola
What does quadrant mean in you own words?
A quadrant is a section of a circle or shape that has been equally divided into those four sections.
If a clock is divided into 12 equal sections How many degrees are there in each section?
There are 360 degrees in a whole circle. Divide into 12 equal sections and you have got 30 degrees in each.
Is a circle straight?
No. No part of a circle is straight.

What does Buddhist symbol Gankyil look like?
A circle divided into three sections by three curved lines, from the circumfrance to the centre point: rather like a yin-yang with three sections.

Is a circle straight?
No. No part of a circle is straight.
What are circle and parabola?
They may be defined in a number of different ways. One possible description is that they are conic sections.
What is the greatest number of parts a circle can be cut into by 7 straight cuts?
Providing that the cuts dont overlap each other then the circle will be divided into 8 parts
What is the measurement of diameter of a circle?
The diameter is the distance from one side of the circle, through the middle, and to the other side. It is a straight line. It is equal to The circumference (the distance around the circle) divided by pi (about 3.1415926536)
How do you get 8 sections by using 3 straight lines and a circle?
I can make maximum of 7 sections ( in addition to 4,5, and 6). To do that, make a plus "+" sigh dividing circle into 4 parts. Now play with 3rd line to make it cut through three quadrants making an additional 3 sections. Hint: start third line passing 0,0 and dividing two opposite quadrants. Keep this line moving into one of the quadrants that hasn't been touched. Once you start sliding down (or up or sideways) on to the quadrant (that wasn't divided) you see a total of 7 sections!
How is a tangent different from a chord?
A tangent is a straight line that touches the outside circumference of a circle at one point whereas a chord is a straight line within a circle that spans its circumference.
