How do you divide a circle with 9cm diameter in three equal parts?
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.
How do you divide a circle into 3 equal parts?
A circle has 360 degrees inside it, 360/3=120. Cut the circle up so that there are three 120 degree angled wedges and you have 3 equal parts.
How do you draw a sphere?
step 1: make a circle with a compass step 2: divide the circle into 4 equal parts step 3: draw curved lines
How do you describe the parts of a fraction to children?
You draw a circle, and divide it into several equal parts - for example, 4 equal parts. Then you select some of those parts - for example, 3, by drawing them in some special color or shading them. Using a circle is convenient, because then, even if you divide it into pieces, it is visually quite clear that it is part of something greater.
How many different sections can a circle be divided into by 5 straight lines?
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)
