2 answers:
Answer:
Step-by-step explanation:
The equation for a circle in standard form is , where h and k are the coordinates of the center. Our center has an h value of -2 and a k value of -3 with an r value of 3. Fitting those values into our standard form of a circle we have . Subtracting a negative is the same as adding, and squaring the right side gives us 9, so the equation is . Third choice from the top.
