What is the general form of the equation of a circle with its center at (2, 1) and passing through (4, 1)?
x2 + y2 − 4x + 2y + 1 = 0
x2 + y2 + 4x − 2y + 1 = 0
x2 + y2 + 4x − 2y + 9 = 0
x2 − y2 + 2x + y + 1 = 0

Best ResponseYou've already chosen the best response.02 is the distance. so 2 is the radius. So what's the equation for a circle with radius 2 and center at (2, 1)?

Best ResponseYou've already chosen the best response.0you've been asking these circle questions all day, and on just about every one of them someone's posted the equation where all you have to do is plug in the radius and center, and you always say you understand. please don't tag me if you're not even willing to make an attempt. This isn't my homework

Best ResponseYou've already chosen the best response.2Standard form equation for a circle with center (h,k) and radius r is: (x−h) 2 +(y−k) 2 =r 2 So you have the center, now you just need the radius. Well, given the center and a point on the circle, the radius is just the distance between those 2 points. so use the distance formula to find the distance between those 2 points, which is your r: d=(x 1 −x 2 ) 2 +(y 1 −y 2 ) 2 − − − − − − − − − − − − − − − − − − √ Then plug your center point coordinates, and your r, back into the circle equation that I gave you above.

Best ResponseYou've already chosen the best response.2Standard form equation for a circle with center (h,k) and radius r is: \[(x−h) ^{2} +(y−k) ^{2} =r ^{2}\] So you have the center, now you just need the radius. Well, given the center and a point on the circle, the radius is just the distance between those 2 points. so use the distance formula to find the distance between those 2 points, which is your r: \[d=\sqrt{(x _{1} −x _{2} ) ^{2} +(y _{1} −y _{2} ) ^{2} } \] Then plug your center point coordinates, and your r, back into the circle equation that I gave you above.
