Question

The distance between two tangents to a circle which are parallel to each other is $12$ cm. The radius(in cm) of circle is ______.

Answer 1

Solution:-

Given that the distance between two tangents parallel to each other to a circle is 12 cm.

Two parallel tangents to a circle are found when the line joining the point of contacts are diameter.

$\therefore d=12\text{cm}$

$\Rightarrow r=\frac{d}{2}=\frac{12}{2}=6\text{cm}$
