Find the equation of the circle passing through the Points (4, 1)and (6, 5) and whose centre is on the line is 4x + y = 16 |
|
Answer» Given POINTS, (4,1),(6,5) EQUATION of circle (x-h)2+(y-k)2=r2 - (4-h)2+(1-k)2=r2 (1) → (6-h)2+(5-k)2=r2 (2) solving the above 2 EQUATIONS, we get, h+2k=11 (3) given, 4h+k=16 (4) solving the above 2 equations, we get, h=3,K=4 substituting the above values in (1), we get, (4-3)2+(1-4)2=r2 r=10 Hence, the equation is, 46 14 1 97% 142 8 x 5.0 (x-3)2+(y-4)2=(10)2 X2+y2-6x-8y+15=0 |
