Answer:

17cm

Radius of circle = 8cm

SP=RP=15cm(Tangents drawn from same external point are equal)

Let the distance between Centre of circle and external point be x.

Using Pythagoras theorem ,

x {}^{2}  =  {15}^{2}  +  {8}^{2}

 {x}^{2}  = 225 + 64

 {x}^{2}  = 289

x \:  =  \sqrt{289}

x = 17

Therefore,distance between centre and point P is 17cm.Option(3).
