As one of the contributors noted, I would like to also state that if these are home works that students are asked to do by their teachers (school work) it defeats the purpose of the homework. Instead of solving the problem I will give hints. Staff who monitor and moderate this site, please give contributors some guidelines please.
Find the area of the 20cm diameter circle. Divide it by the area of the 6mm diameter circle. If you get a whole number, that is the answer. If not round it down to the nearest whole number.
zero
True, but many people nowadays like semi-circles instead.
It varies. There is no set diameter of a circle.
1^2 or 2^2 or 3^2 or 4^2.... and it goes on...where diameter of circle is equal to the side of square divided by square root of total numbers of circles.. eg : side of square = 10 no of circles = 2^2 square root = 2 therefore diameter = 10/2=5.
Multitude
Circle is a shape. We have gotten to know a lot from circles. Because of circles, we get PI, radius, diameter, circumference, and other things. Circles fall into geometry, which is math. We can make many mathematical equations from circles.
zero
There are an infinite number. If you draw two great circles, no matter how close together they are, I can always draw a great circle ... or 2 or 3 or 10 ... between them.
Circumference of a circle = (pi) x diameter of the circle therefore,pi = Circumference/diameter or plot a graph of circumference against diameter using many circles and the slope of the line on the graph would be equal to pi.
True, but many people nowadays like semi-circles instead.
If you divide 600 mm by 37 mm, you will know how many circles you can place side-by-side. In other words, you would be comparing the diameters.If on the other hand you want to compare the area, you have to square the previous result.
a circle has 4 sides
It varies. There is no set diameter of a circle.
The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.
Pi comes up endlessly in mathematics, it is associated with a great many things other than circles. Of course, it is still true that pi by definition is the ratio of the circumference to the diameter of a circle.
I guess 3 . Take these 3 points 2 at a time . These two points would be the diameter of the circle .
1^2 or 2^2 or 3^2 or 4^2.... and it goes on...where diameter of circle is equal to the side of square divided by square root of total numbers of circles.. eg : side of square = 10 no of circles = 2^2 square root = 2 therefore diameter = 10/2=5.
