Question

If (2,5) is an interior point of the circle x2 + y2 -8x -12y +P = 0 and the circle neither cuts nor touches any one of the co-ordinate axes then-
(A) P belongs to (36,47)
(b) P belongs to (16,47)
(c) P belongs to (16,36)

Answer 1

Step-by-step explanation:

or given conditions

4+25 -16 - 60 +p<0

p < 47

4^2 + 6^2 - p <16

=> p>36

Hence , p belongs to ( 36 , 47 )
