The largest among the distances from the point P(15,9) to the points on the circle x^2+y^2-6 x-8 y-11=0 is
Options
- A12
- B13
- C19
- D7
Correct answer
C. 19
Step-by-step solution
x^2+y^2-6 x-8 y-11=0, P(15,9) Centre (C)=(3,4) Radius = 9+16+11 =6 ; C P= (15-3)^2+(9-4)^2 =13 Greatest distance =13+6=19
