Question

Use the equation to identify the center and radius of the circle (X+3)^2+(y-7^2=11

Answer 1

To find the radius od the circle using (X+3)²+(y-7)²=11

(x-a)²+(y-b)²=r² is the equation for a circle in a Cartesian plane

the center is given by c= (a,b) so the center would be (-3,7)

and to find the r use

11 =r²

√11 = r

3.31 = r
