In two concentric circles, a chord of length `8cm` of the larger circle touches the smaller circle. If the radius of the larger circle is `5cm` then find the radius of the smaller circle.

The sum of the radii of two concentric circles is 48. If a chord of length 36 of the larger circle is cut into three equal pieces by the smaller circle,then the radius of the larger circle is centric circles is

If two concentric circles,a chord of length 24cm of larger circle becomes a tangent to the smaller circle whose radius is 5cm. Find the radius of the larger circle.

In two concentric circles, a chord of length 24cm of larger circle becomes a tangent to the smaller circle whose radius is 5cm. Find the radius of the larger circle.

In two concentric circles,a chord of length 24cm of larger circle becomes a tangent to the smaller circle whose radius is 5cm. Find the radius of the larger circle.

In two concentric circles, a chord of length 24 cm of larger circle becomes a tangent to the smaller circle whose radius is 5 cm. Find the radius of the larger circle.

If two concentric circles, a chord of length 40 cm of larger circle becomes a tangent to the smallor circle whose radius is 15 cm. Find the radius of the larger circle.

The adjoining figure shows two circles with the same centre.The radius of the larger circle is 10cm and the radius of the smaller circle is 4cm.

In two concentric circles, a chord of length 16 cm of larger circle becomes a tangent to the smaller circle whose radius is 6 cm. Find the radius of the larger circle.

Prove that in two concentric circles, the chord of the larger circle which touches the smaller circle is bisected at the point of contact.
