Question

2. For the circle with equation (x – 2)2 + (y + 3)2 = 9, answer each question:
a) What are the coordinates of the center?
b) What are the radius and diameter of the circle

Answer 1

For circles in the form of \(\Large(x-\color{green}h)^2+(y-\color{green}k)^2=\color{blue}r^2\), the center is \(\large(\color{green}h,\color{green}k)\) and the radius is \(\large\color{blue}r\) :)

Answer 2

so the radius would be 9

Answer 3

? r^2 = 9
radius = r
