Question

Write the equation of a circle with a center at (-6, 9) and a radius of 12?

Answer 1

let (-6,9) be (h,k), and let the radius = r

use the formula (x-h)^2 + (y-k)^2 = r^2

Answer 2

So, (x+6)^2 + (y-9)^2=12^2? Do I change the 12^2 to 144?

Answer 3

yes, you change 12 to 144, and then your complete equation is?

Answer 4

i mean 12² to 144

Answer 5

u get?

Answer 6

I get. (x+6)^2 + (y-9)^2= 144, right?

Answer 7

yes, that is right

Answer 8

and that is it as well. you are done

Answer 9

Thank you!

Answer 10

anytime!
