From the given figure
We can count the squares in 1/2 the circle then multiply it by 2
There are about 45 squares in the half of the circle
Then 45 x 2 = 90
The number of the squares inside the circle is about 90 squares
Let us try to find the area of the circle using the rule
[tex]A=\pi r^2[/tex]
Let us find the length of the radius from the figure
The diameter of the circle is about 10 squares
Then its radius = 10/2 = 5 units
[tex]\begin{gathered} A=\pi(5)^2 \\ A=3.141(25) \\ A=78.53\text{ square unit} \end{gathered}[/tex]
The area of the cookie is about 79 square unit
