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 circle, prove that a chord of larger circle which is tangent to smaller circle is bisected at the point of contact.

Out of the two concentric circle the radius of the outer circle is 5 cm and the chord AC of the length 8 cm is a tangent to the inner circle find the radius of the inner circle.

The adjoining figure shows two circles with the same centre. The radius of the larger circle is 10 cm and the radius of the smaller circle is 4 cm.Find: (a) the area of the larger circle (b) the area of the smaller circle (c) the shaded area between two circles ( π=3.14)

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

A chord 10 cm long is drawn in the circle whose radius is 5 sqrt2 cm. Find the area of both the segments

Two circles have an external tangent with length 36 cm. The shortest distance between these circles is 14 cm. If the radius of the longer circle is 4 times the radius of the smaller circle then the radius of the larger circle in cms is

If radii of two concentric circles are 4 cm and 5 cm , then length of each chord of one circle which is tangent to the other circle, is

A point P is 13cm from the centre of the circle. The length of the tangent drawn from P to the circle is 12 cm. Find the radius of the circle.

The length of a tangent from a point A at distance 5 cm from the centre of the circle is 4 cm. Find the radius of the circle.

The length of a tangent from a point A at distance 5 cm from the centre of the circle is 4cm. Find the radius of the circle.
