Question 317023
Garden Area Problem. A designer created a garden
from two concentric circles whose equations are as follows:
(x+2)small 2 +(4-6) small 2 =16 and (x + 2) small 2 +(y -6) small 2 =81 
(I hope yu can understand this)
--------------
I think you meant:
{{{(x+2)^2 +(y-6)^2 =16}}}
 and {{{(x+2)^2 +(y-6)^2 =81}}}
-----------
Those are 2 concentric circles, radius 4 and radius 9
What about them?
