You have two circles, one with radius r and the other with radius r. you wish for the difference in the areas of these two circles to be less than or equal to 5\pi. if r+r=10, what is the maximum difference in the lengths of the radii?

maximum difference of radii =

Step-by-step explanation:

We know that area of circle is given by

For circle with radius 'r' we have

For circle with radius 'R' we have

Now according to given condition we have

Thus maximum difference of radii =

the answer is d. (1.2, -4.7) on edgn

hope this !
