Question

Find the area of shaded region in given figure 14 cm and 7 cm
​

Answer 1

Given:

The radii of circles are 14 cm and 7 cm.

To find:

The area of the shaded region.

Solution:

Area of a circle is

`Area=\pi r^2`

From the given figure, it is clear that

Area of shaded region = Area of larger circle - Area of smaller circle

=
`\pi (14)^2-\pi (7)^2`

=
`(22)/(7)* 14* 14-(22)/(7)* 7* 7`

=
`616-154`

=
`462`

Therefore, the area of the shaded region is 462 sq. cm.
