Question

If the distance of the centre of the circle from a point outside the circle
is 10 cm and the length of the tangent is 8 cm, then the radius of the circle will be:​

Answer 1

Length of the tangent dawn to the circle from point P will be 6 cm.

Step-by-step explanation:

By the theorem, tangent drawn from a point P to the circle at point T is always perpendicular to the radius joining points O and T.

By Pythagoras theorem in ΔTOP,

TP² + TO² = OP²

TP² = OP² - TO²

TP² = 10² - 8²

TP =$\sqrt{100-64}=\sqrt{36}$

TP = 6 cm

Therefore, length of the tangent TP will be 6 cm.
