Question

(08.01 LC)Find the area of a circle with a diameter of 20 inches. Use 3.14 for pi.(1 point)

Answer 1

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
