Question

A circle is drawn on a coordinate plane with the center point at (0,3)
and a radius of 3. Derive the equation of the circle from the given information. Fill in the missing information in the following equation.(2 points)
( x−

) 2+
( y−

) 2=

Answer 1

(x − 0)^2 + (y − 3)^2 = 9

(Equivalently x^2 + (y − 3)^2 = 9, since the center is (0,3) and r^2 = 3^2 = 9.)
