Find the equation of the circle centered at (1,-4) with radius 3. Write your equation in the form "(x - h)^2 + (y - k)^2 = r^2".

The equation of the circle is (x - 1)^2 + (y + 4)^2 = 3.

hey sorry thats wrong

This is an extremely easy question.

The centre is (h,k) and the radius is r.

Do the substitution yourself.

thank you, i just started this unit...

So what?

You want people here to do your homework for you instead of you looking at your notes?

You still haven't bothered to tell us what the answer is.

sorry didnt mean to offend anyone i was just wondering if i could get a explanation instead of a rude statement not all of us are geniuses i thought this forum was supposed to help people

Easy peezy : when given the center and the radius

Change the signs on the center coordinates and square the radiius

This leads to

(x - 1)^2 + ( y + 4)^2 = 9

thank you :)
