Answer:
(x+4)^2 +(y+6)^2 = 9
Step-by-step explanation:
The equation for a circle is given by
(x-h)^2 + (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
(x- -4)^2 + (y--6)^2 = 3^2
(x + 4)2 + (y + 6)2 = 9 is the equation of this circle.
The standard equation of a circle with center (h, k) and radius r is
(x-h)^2 + (y-k)^2 = r^2. Please use " ^ " for exponentiation.
We can immediately discard the 1st and 3rd answers, since the radius squared is 3^2, or 9.
Comparing
(x - h)^2 + (y-k)^2 = r^2 to
(x + 4)2 + (y + 6)2 = 9 shows that h = -4 and k = -6, as well as r = 3.
Therefore, (x + 4)2 + (y + 6)2 = 9 is the equation of this circle.
I don't see how the numbers on the chart work with the table because I
got 1(1), 3(2,2,2), 6(4,4,4,4,4,4), 10(6,6,6,6,6,6,6,6,6,6), 5(8,8,8,8,8), 3(10,10,10) ,1(12)
that is how i see the chart, sorry if i got it wrong.
