Question

C= (_1/2),r=9 find the equation of the circle with center c and radius where

Answer 1

Answer: The equation of the circle is...

3x² + 3y² − 3x − 54y - 223 = 0

Step-by-step explanation: Centre of the circle=(-f/2,-g/2)=>(-1/2,-9)

substitute it in the basic circle equation

and the with the formula f2 + g² radius find "C" -C=
