Answer 1

Answer:

21.98 cm square

Step-by-step explanation:

so the remaining part area = the area of big circle - the area of small circla

Answer 2

Answer:

$21.98 \: {cm}^{2}$

Step-by-step explanation:

First, find the area of the circular sheet.

It's radius is given as 4cm,

then,

$area = \pi {r}^{2}$

From this, area= 50.24 cm^2

Now, area of the small circle which is removed will be,

with given radius as 3cm,

and the same formula,

Area= 28.26cm^2

Now to find area of the remaining sheet, subtract the area that was taken out from the area of the original sheet,

Area of remaining sheet = 50.24-28.26 = 21.98cm^2

This is the area of the remaining sheet.
