(x -5)2 + (y + 2)2 = 64

The radius of the circle is ________ units?

Answer 1

\[(x-h)^{2} + (y-k)^{2} = r ^{2}\]
is the equation of a circle with center (h,k) and radius r...
compare youe equation with this equation and you can easily get the answers....

Answer 2

(x-25) + (y + 4) = 64? is that right or do i divide 64 by 2?

Answer 3

\[r ^{2} = 64\]
then r is..????

Answer 4

8?

Answer 5

correct....

Answer 6

thank you :)
