Question

PLEASE HELP ASAP!! what is the equation of a circle if, Center (3, -2), radius = 5

Answer 1

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

Answer 2

this is for a circle with c(h,k)

Answer 3

the general form of a circle is

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

with centre at (h, k) and radius r

in your question you have centre (3, -2) and r = 5

just substitute

Answer 4

now you can substitue
