find the radius r and the center (h,k) of the following circle
2 2
3 (x-3) + 3y =75
Hi !
Use ^2 to write exponents
You know that the equation of a circle, of center and of radius R is :
Therefore, try to make appear that form.
The reflex will be to divide the whole equation you have by 3, in order to get
Then, note that .
Recognize in your equation and R
