Asked by Soly
Could you please check some of my Algebra problems please?
Write the standard form of the equation of the circle with the given center and radius.
1. (-7,4);8
I got (x+7)^2 + (y-4)^2=64
2. (-7,10); square root of 17
I got (x+7)^2 + (y-10)^2=17
3. (0,0); 2 square root of 2
I got x^2+y^2=8
Find the center and the radius of the circle
7. (x-4)^2 + (y-1)^2=9
I got (4,1) as the center and the radius 3.
