Answer:
Explanation:
area of square = L x L
=10 x 10 = 100
area of circle = π x r x r
to get r, divide the square into two triangles
then use Pythagoras theorem to get the hypothenuse
(10x10)+(10x10)=hxh
200=h²
√200=h
h=14.14
h=diameter
therefore, the radius=7.07
now back to the area of a circle
π x7.07²
=49.98π
area of shaded part=area of circle - area of square
=49.98π- 100
