Question

The square below has area 100. Find the area of the shaded region.

Answer 1

Answer:

21.46

Step-by-step explanation:

Start with the square

$A = a^{2} \\100 = a^{2}\\10 = a$

Each side of the square is 10

This also means the diameter of the circle is 10, with a radius of 5

$A = \pi r^{2} \\A = \pi 5^{2} \\A = 78.54$

Now substract the area of the circle from the square

x = 100 - 78.54
