You can put this solution on YOUR website! .

~~~~~~~~~~~~~~~~~~
The formula for the area of a sphere is presented INCORRECTLY in your post.
Also, you started from a sphere, but then you suddenly switched your question to a circle.
Let me remind you that a sphere and a circle are two different figures, objects and conceptions.
It is a HUGE MISTAKE to think that they are the same.
Next time try to concentrate your attention on a subject, when you write to this forum.
Always remember that there are EXPERTS at this forum, who read your posts ATTENTIVELY (probably, in distinction of you . . . ).
Therefore, GIBBERISH will not pass here.
