Question

Find the equation of a circle that has its center at (-4, 3) and has a radius of 5.

(x+ 4)2+ (y- 3)2= 25
(x- 4)^2+ (y- 3)^2= 25
(x+ 4)^2+ (y+ 3)^2= 25
(x- 4)^2+ (y+ 3)^2= 25

Answer 1

The equation of a circle is:
\[(x-h)^2+(y-k)^2=r^2\]

Answer 2

(h,k) is the center and r is the radius.

Answer 3

sooo its C ?

Answer 4

or actually B, right ?

Answer 5

neither of them

Answer 6
