Question

find the equation of the circle with the center (-2,9) and radius of 3

plz show work

Answer 1

(x+2)^2+(y-9)^2=9

Answer 2

just plug what you were given into the standard equation of a circle:
(X-H)^2 + (Y-K)^2=r^2

Answer 3

so te radius is 3?

Answer 4

the radius

Answer 5

you said the radius is 3 in the question.

Answer 6

it is three in the question.. i guess im confused

Answer 7

look at the equation of the circle, what happens to the radius when we plug it in, radius is represented by r

Answer 8

center
\[(h,k)\] radius
\[r\] circle is
\[(x-h)^2+(y-k)^2=r^2\] as lagrange said

Answer 9

thnks guys
