Question

Find the equation of the following circles having the center (3,5) and radius 5 units​

Answer 1

The equation of circle with center (h,k) and radius r units is  (x−h)  

2 +(y−k)  

2 =r  

2

 The equation of the circle with center (2,3) and radius 5 units is  ⇒(x−2)  

2 +(y−3)  

2 =5  

2 ⇒x  

2 −4x+4+y  

2 −6y+9=25⇒x  

2 +y  

2 −4x−6y−12=0
