Question

Write the equation of a circle whose diameter is 12 and whose center is at (-6,-3)?

Answer 1

Answer:

The standard form of the equation of a circle is,

                       (x - h)² + (y - k)² = r²

where the center is at (h, k) and its radius is r. From the givens above, the equation of the circle is,

                        x² + y² = (12/2)²

or equal to x² + y² = 36.
