Area of a sector of angle p^@ of a circle with radius R is

A circle with radius 2 is placed against a right angle.A smaller circle is also placed as shown in the adjoining figure.The radius of the smaller circle is:

O is the centre of the smaller circle,O' is the centre of bigger circle.CD is tangent to the smaller circle,Find the radius of the smaller 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)

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)

If theta is the angle (in degrees) of a sector of a circle of radius r, then area of sector is
