 HalloI would like to solve a circle equation. I use Mathematica with Raspberry.1.) I defined variables c=-90, d=27, r=10 , x=33,6777 2.) I wrote: NSolve[(x - c) ² + (y - d)² == r² , {y}, Reals] 3.) I'm interested in y4.) as a result I receivedNSolve::ratnz: NSolve was unable to solve the system with inexact coefficients. The answer was obtained by solving a corresponding exact system and numericizing the result. {{y -> (0.0001 (-966777. .b2 + 10000. r.b2))/.b2}}5.) I expected for y=-82,556Can anybody help me.

 You seem to be asking "If I have a circle with radius 10 centered at {-90, 27} what is its height at x=33.677. Put like that it should be pretty obvious that there will be no solution except for -100
