Question

Look at the pic to see the question When counting the squares inside the outline, make sure to make your best guess when including partial squares. ** 2 partial squares can equal 1 square **

Answer 1

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

`A=\pi r^2`

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

`\begin{gathered} A=\pi(5)^2 \\ A=3.141(25) \\ A=78.53\text{ square unit} \end{gathered}`

The area of the cookie is about 79 square unit
