A poor artist on the street makes funny cartoons for children and earns his livings. Once he made a comic face by drawing a circle within a circle, the radius of the bigger circle being 30 cm and smaller being 20 cm as shown in the figure. What is the area of the cap given in this figure? What qualities of this artist being reflected here.

If the radius of the circle is 6 cm, then the area of the shaded region shown in the figure is

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

In the given figure, PQR is a quadrant whose radius is 7 cm. A circle is inscribed in the quadrant as shown in the figure. What is the area (in cm^(2) ) of the circle

The difference between the radii of the smaller circle and the bigger circle is 7 cm and the difference between the areas of the two circles is 1078 sq cm. What is the radius of the smaller circle in cm?

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

As shown in the figure , radius of the given circle is 21 cm and angleAOB=120^(@) . The find the area of segment AYB .
