Question

Find the equation of the circle of center (-1/2,-9) and radius r=5

Answer 1

Answer:

the required eqn :-

(x+1/2) ^2+ (y+9) ^2 = 5^2

$x^{2} +\frac{1}{4} +x+y^{2} +81+18y = 25\\x^{2} +y^{2}+ x +18y =183$

Step-by-step explanation:

Answer 2

Step-by-step explanation:

the required eqn :-

(x+1/2) ^2+ (y+9) ^2 = 5^2

\begin{gathered}x^{2} +\frac{1}{4} +x+y^{2} +81+18y = 25\\x^{2} +y^{2}+ x +18y =183\end{gathered}
