Answer 2

Given :

• From a circular sheet of radius 4 cm, a circle of radius 3 cm is removed.

　

To find :

• Find the area of the remaining sheet. [Use π =3.14].

　

Using formula :

★ Area of circle = πr².

　

Calculations :

→ Area = 3.14 × 4 × 4

→ Area = 3.14 × 4²

→ Area = 50.24

　

→ Area = 50.24 - 28.26

→ Area = 21.98 cm²

　

Therefore, 21.98 cm² is the area of the remaining sheet.
