Tangent = 13 cm
Radius = 3cm
Tangent is perpendicular and radius is base ( Because line drawn from centre to the point of contact of tangent is perpendicular)
So by Pythagoras theorem
13^2 + 3^2 = H^2
169 + 9 = H^2
178 = H^2
H = √178
H = 13.34 cm (approx.)
So the distance of the point from centre is 13.34 cm.
