The formula for the surface area  of  sphere is A=pr2.Rerrange the formula to solve for r,the  radius of the circle.
~~~~~~~~~~~~~~~~~~



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.
