Answer:
Ans. 25
Step-by-step explanation:
The equation of a circle in coordinate system is given by
(x-h)²+(y-k)²=r²
where (h,k) is the centre of the circle and r is the radius.
So by substituting the values,
(x-(-5))² + (y-(8)²= 3√3²
So, (x+5)² + (y-8)²= 89 is the equation of the circle.
You can expand it if you want, but the form given above is easier to remember and use.
Hope this helps
