What is the standard form of the equation of a circle that has its center at (-2, -3) and passes through the point (-2, 0)?

Question

mathmale · Answer

I'll share some background info with you here:

1.  The standard form of a circle with center at (0,0) and radius r is$$x^2+y^2=r^2$$
2.  The std. form of a circle with center at (h,k) and radius r is $$(x-h)^2+(y-k)^2=r^2$$

If you'd substitute the given info into the 2nd equation properly, you'll be able to calculate the radius, r.

Then write the equation of this circle including the now-known value of r.
