Question

Which equation is the equation of a 10cm radius circle with it's center at (3, -6)

Answer 1

\((x-h)^2+(y-k)^2=r^2\)

H is the x value of the coordinate, K the y value, and R = radius

Answer 2

so(X - 3)^2 + (y - -6)^2 = r^2

Answer 3

but the two negatives would turn into a positive

Answer 4

Close

(x-3)^2 is correct

(y - - 6)^2 should become (y + 6)^2

Answer 5

And for the r^2, you would but 10^2 = ?

Answer 6

20

Answer 7

no 10^2 = 10 * 10 not 10 * 2

Answer 8

oh sorry 100

Answer 9

Ok so the final answer is:

\((x-3)^2+(y+6)^2=100\)
