Question

From a point Q, The length of the tangent to a circle is 24 cm and the distance of Q from the centre is 25 cm . Find the radius of the circle

Answer 1

Answer:

Answer in given in the picture

hope it helps you

Answer 2

Answer:

the radius of the circle=7

Step-by-step explanation:

Let QP be the tangent, such that, Point of contact is P.

Length of the tangent to a circle = 24cm

$$PQ=24cm$$

Let O be the centre of the circle.

OQ=25cm

We have to find the radius OP

Since QP is tangent

OP perpendicular to QP (Since, Tangent is Perpendicular to Radius at the point of contact)

So, ∠OPQ=90

∘

So apply Pythogoras theorem to right triangle, OPQ;
