Question

Find the equation of the circle with center (2, -6) and radius 4

Answer 1

equation of circle (x- h)^2 + (y - k)^2= r^2 where (h,k) is center & r is radius

Answer 2

We have center (2,-6) & radius r=4 so just plug values in above equation ..

Answer 3

Do u get it ?

Answer 4

no it wasnt right but thanks for trying

Answer 5

Actually, tgawade is correct. However, if you are looking for the general form of this equation, you will have to multiply it out.

\[(x-2)^{2} + (y+6)^{2}=4^{2}\]

The general form should look like this\[x ^{2} + y ^{2} -4x +12y +24= 0\]
