Question

Which of the following is the equation for a circle with a radius of r and center at (h, 3)?

A. x2 + (y-3)2 = h2
B. (x + h)2 + (y + 3)2 = r2
C. (x - h)2 + (y - 3)2 = r2
D. (x - h)2 + (y -3)2 = r

Answer 1

Answer 2

there is a `standard form` for circle too

Answer 3

do you have notes handy ?
can u look up quick and see if u can find the `standard form of circle` ? :)

Answer 4

(x−h)2+(y−k)2=r2

Answer 5

yes ! thats the equation :

center = (h, k)
radius = r

Answer 6

compare the options with this standard form, and see if u can figure it out

Answer 7

i knew that lol
