Question

What is the equation of the circle with center (2,6) radius 5?

Answer 1

the equation of a circle is:
(x-h)^2+(y-k)^2 = r^2
where (h,k) is a point on the circle and r is the radius
what can you plug into the formula with the given information?

Answer 2

@Maymay07 The equation of a circle with center (h, k) is given by\[(x -h)^{2}+(y -k)^{2}=r ^{2}\]where (h, k) is the center of the circle, NOT a point on the circle as @etemplin stated, and r is the radius of the circle.

Answer 3

oh...sorry
my mistake

Answer 4

That's OK, it happens but you must pay more attention to detail, especially when you're trying to teach someone.

Answer 5

Thank you :)
