In the figure, the radius of the larger circle is 2 cm and the radius of the smaller circle is 1 cm and the larger circle passes through the centre of the smaller circleThe length (in cm) of the chord AB is :

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(a) the area of the larger circle (b) the area of the smaller circle (c) the shaded area between the two circles. ( pi = 3.14)

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)

In the given figure,diameter of larger semi- circle is 14cm and radius of smaller semi- circle is 3.5cm. find :

In the adjoining figure the diameter of the larger circle is 10 cm and the smaller circle touches internally the lager circle at P and passes through O, the center of the larger circle, Chord SP cuts the smaller circle at R and OR is equal to 4 cm. What is the length of the chord SP ?

In the figure below, the radius of the bigger circle is (sqrt(2) +1) cm and the radius of all the smaller circles are equal. Each of the smaller circles touches two of the other three smaller circles and the larger circle as shown. Find the area (in cm2) of the shaded portion.

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