Question

Which is the equation of a 10 cm radius circle with its center at (3, –6)?

(x + 3)^2 + (y – 6)^2 = 20


(x – 3)^2 + (y + 6)^2 = 100


(x – 3)^2 + (y + 6)^2 = 20


(x + 3)^2 + (y – 6)^2 = 100


My answer: (x – 3)^2 + (y + 6)^2 = 100

Answer 1

\[(x-h)^{2}+(y-k)^{2} = r \]

where the center is (h,k)

h = 3
k = -6

\[(x-3)^{2}+(y+6)^{2} = (10)^{2}\]
