Question

Diameter of circle is 10 , point p lies outside the circle and two tangent passes through p each is 12 cm then find the distamce that p lies from centre f circle

Answer 1

Let the measurement of each tangent = 12 cm
Radius = 1/2 diameter = 10/ 2 = 5cm
Distance from Centre to point P is hypotenus of triangle FTP.
Angle T forms 90 degree
Distance PF^2 = PT^2 + TF^2
PF^2 = 144 + 25
PF^2 = 169
PF = 13
THEREFORE DISTANCE = 13 cm
