**Circles ncert solutions Chapter 10 Exercise 10.2 Question 1**

**1.** **From a point Q, the length of the tangent to a circle is 24 cm and the distance of Q from the center is 25 cm. The radius of the circle is:**

**(A) 7 cm (B) 12 cm (C) 15 cm (D) 24.5 cm **

It is given that BQ = 24 cm and OQ = 25 cm

is right angled triangle because tangent is always perpendicular to radius of the circle.

Therefore, we can apply Pythagoras theorem on

By, Pythagoras theorem, we can say that

cm

**Therefore, radius of circle is equal to 7 cm.**

**Therefore, answer is (A)**
