Question

The road sign lets drivers know there are bicycle lanes for bicyclists. The sign has a radius of 8 inches. What is the area of the sign?

Answer 1

The radius of circle is r = 8 inches.

The formula for the area of circle is,

`A=\pi(r)^2`

Determine the area of the sign.

`\begin{gathered} A=\pi(8)^2 \\ =(22)/(7)\cdot64 \\ =201.1428 \\ \approx201.1 \end{gathered}`

So area of the sign is 201.1 inch square.
