From a circular sheet of radius 4 cm, a circle of radius 3 cm is removed. Find the area of the remaining sheet. (Take π = 3.14)

Dear Student

From the question it is give that,
Radius of circular sheet R = 4 cm
A circle of radius to be removed r = 3 cm
Then,
The area of the remaining sheet =πR2-πr2
=π(R² –r²)
= 3.14 (4² - 3²)
= 3.14 (16 - 9)
= 3.14 × 7
= 21.98 cm²
So, the area of the remaining sheet is 21.98 cm²

Thanks
