In the figure, the area of the shaded region is 243π cm2. what is the value of x?

Answer

Find out the  value of x.

To  proof

Formula

As given

Radius  of the bigger circle = 18cm

Radius  of the smaller circle =x

As shown in the diagram

shaded area = Area of the bigger circle - Area of the smaller circle

than we have

243 = 324 - x²

324- 243 = x²

√81 = x

9cm = x

the value of x is 9cm .

Hence proved
