This is what I got:
x^2+y^2=1
x^2+y^2=4
x^2+y^2=9
x^2+y^2=16
x^2+y^2=25
x^2+y^2=36
x^2+y^2=49
x^2+y^2=64
x^2+y^2=81

I couldn’t figure out how to shade the circles, however. I spent a long time pressing every button I could to try to figure it out and came back unsuccessful.

Great! All you have to do to shade is to change the = sign to a <= sign!

x^2+y^2<=16
x^2+y^2<=25
x^2+y^2<=36
