Answer:
D. r = √7 and (6, -4)
Step-by-step explanation:
Since, the standard equation of a circle is,
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where, (h,k) is the center of the circle and r is the radius of the circle,
Here, the given equation of the circle,
[tex](x-6)^2+(y+4)^2=7[/tex]
[tex]\implies (x-6)^2+(y-(-4))^2=(\sqrt{7})^2[/tex]
By comparing,
The radius of the circle, r = √7 unit,
And, center = (6,-4)
Hence, option 'D' is correct.
