If the point (1, 4) lies inside the circle and the circle does not touch or intersect the coordinate axes, then the set of all possible values of p is the interval :
As we learnt in
General form of a circle -
- wherein
centre =
radius =
Given
12 + 42 - 6 - 40 + p < 0
p < 29
also
(since it shouldn't touch y-axis)
34 - p < 9
p > 25
so, p (25, 29)
