Write the standard equation of the circle with center (-3, 5) and a diameter of 14.
Answer

(x + 3)2 + (y – 5)2 = 49

(x + 3)2 + (y – 5)2 = 7

(x – 5)2 + (y + 3)2 = 49

(x – 3)2 + (y + 5)2 = 196

jtvatsim · Answer

The standard equation of a circle is $$(x - h)^2 + (y - k)^2 = r^2$$ Note that h and k are just the center of the circle $$(h,k) = (-3,5)$$ and you can find the radius r using the diameter information.
Then, just plug everything in.
