# Q. 5.     From a circular sheet of radius $4\; cm$, a circle of radius $3\; cm$ is removed. Find the area of the remaining sheet.(Take $\pi =3.14$)

G Gautam harsolia

We know that

Area of circle $= \pi r^2$

Area of circular sheet with radius 4 cm $= \3.14 \times (4)^2 = 50.24 \ cm^2$

Area of circular sheet with radius 3 cm $= \3.14 \times (3)^2 = 28.26 \ cm^2$

Now,

Area of remaining sheet = Area of circle with radius 4 cm - Area od circle with radius 3 cm

$= 50.24 - 28.26 = 21.98\ cm^2$

Therefore, Area of remaining sheet is  $21.98\ cm^2$
