Question

Find the coordinates for the center and length of radius for this circle.

(x + 3)2 + (y - 5)2 = 25

center ( ,)

radius ____

Answer 1

In an equation like this:

\(\Large \color{Black}{\Rightarrow (x - h)^2 + (y - b)^2 = r^2 }\)

r is the radius.
(h,b) are the center co-ordinates.

Answer 2

(-3,5) are center co-ordinates and 5 is the radius.

Answer 3

thanks!

Answer 4

5 is the radius because r^2 = 25 and r = 5

Answer 5

Yw :)

Answer 6

wait isnt it (3,-5)?

Answer 7

Nope, it would've been see if the equation of a circle was (x + h)^2 + (y + b)^2 = r^2

Answer 8

oh ok:D

Answer 9

Here it is (x - h)^2 + (y - b)^2

Answer 10

:P

Answer 11

(x - 3)2 + (y - 5)2 = 8
how about here^^
now would it be -3 ,-5??

Answer 12

No, 3,5 only

Answer 13

or both positive 3,5?

Answer 14

oh ok:)

Answer 15

Yep...positive
