Question

Given circle: x2 - 9x + y2 = 4.75, the equation written in standard form would be:

A: (x +4.5)2+ y2 = 22.5625

B: (x + 3)2 + y2 = 25

C: (x - 3)2 + y2 = 20.25

D: (x - 4.5)2 + y2 = 25

Answer 1

The answer is option D.
the general equation of circle with center (h,k) and radius r is
${(x - h)}^{2} + {(y - k)}^{2} = {r}^{2}$
