Hi all how can i get a proportion in circles & ellipse.
Eg: i have a circle diameter is X, outside the another circle radius is x2, another elipse have maximum perimeter is x4 & minimum perimeter is x5.
How can get the proportion of the circle & ellipse, when i say to anybody something like this circle & radius is equal to 1:2...... how can i do this reference JPG is given below
melody thanks for your prompt reply.
Forgot X2, X4 & X5
Please check my image, i am created this shape (ITS STANDARD), my center circle (White area) diameter size is X (because this shape some time smaller & larger to media to media ie. i am not mentioned diameter) another circle yellow color, that circle larger than the my white circle, ellipse also larger than the my white circle JPG is attached previous post. My problem is i don't want to given any dimension to this particular shape. If anybody increase the white circle my another circle yellow & ellipse simultaneously increase. i am try to given a some proportion to my audience. how can i given proportion.
In all three cases the equation of the boundary is:
, where is the number of the area.
For the white area and .
For the yellow ring subtract white area where
For the purple area subtract whole other area where
I leave it to you the find the areas.
You can assume that the radius of the smallest circle is 1 and express all other lengths in terms of it. For example, the ratio of the sizes of purple ellipse : yellow circle : white circle can be (1.5 x 1.2) : 1.1 : 1.
i am try something like this,. My white circle diameter is 30 and yellow circle draw similar to diameter to picture eg. 32. Then 32/30 is equal to 1.07 its my proportion to all cases 30, 35 40 any numbers its standard. same way is apply for Elise. is it right way
