Answer 1

Answer:

well I didn't know the exact shape inscribed in the inner square but I found you the area of the shaded part of the circle

Step-by-step explanation:

first of all find total area of circle

$a = \pi \: r^{2}$

diameter of the circle is equal to the side of the square then radius is 10

then area is

$100\pi$

then find the square inscribed

of diagonal equal to diameter

then apply Pythagorean theorem

$2a^{2} = diagonal^{2} \\ a^{2} = \frac{20^{2} }{2} \\ a^{2} = 200 \\ a = 10 \sqrt{2}$

then area of square is

$100\pi \: - (10 \sqrt{2} )^{2} \\ = 114.1592$
