Question

The given figure consists of four small semicircles of equal radii; and two big semicircles of equal radii (each 42cm). Find the perimeter of the shaded region.

Answer 1

Answer:

Step-by-step explanation:

Here is the answer for ur Query

Perimeter of semi circle πr

Radius of the semicircle AC AND CE are equal

So their perimeter of them is 2πr. 2semicircle =a circle

2*22/7*42=264 cm²

And now the perimeter of the 4 small semi circles

Which have a diameter of 42cm

Since AB=BC=CD=ED

so their radii will be 21cm

As their are the 4 semicircle the formula will be 4πr

Now ,

4*22/7*21=264cm

Now the perimeter of 2 bigger semi circle +perimeter of 4 small semi circles will be

264+264 =528cm
