Question

What is the area of the circle to the nearest 10th unit?

Answer 1

First, lets find the radius of the circle.

For a circle inscribed in a square, the diameter of this circle is equal to the side lenght.

D = 4.4

Since the radius (r) is D/2

r = 4.4/2 = 2.2

Now, we can calcule the area of the circle (A), using the following equation:

`\begin{gathered} A=\pi\cdot r^2 \\ A=\pi\cdot2.2^2 \\ A=4.8\pi units^2 \\ Or,\text{ since }\pi=3.14 \\ A=4.8\cdot3.14 \\ A=15.2\text{ }units^2 \end{gathered}`
