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.

Two smaller circles touch a large circle internally and pass through the centre O of the larger circle. If the diameter of the bigger circle is 28 cm, what is the area of the bigger circle which is not enclosed by the two smaller circles (in cm^(2) ) ?
