The area of a circle can be calculated using the following formula:

$A=\pi r^2$

Where

A represents the area

r represents the radius of the circle

π is the number pi, you have to use 3.14 for the calculatins

You have to calculate the area of a circle that has a diameter of 20 inches. The radius of a circle is half the diameter:

$\begin{gathered} r=(d)/(2) \\ r=(20)/(2) \\ r=10in \end{gathered}$

The area of the circle can be determined as follows:

$\begin{gathered} A=3.14\cdot10^2 \\ A=314in^2 \end{gathered}$

The area of the circle is 314in²
