Question

What is the arc length of CD in the circle below?

Answer 1

Solution

$\begin{gathered} \theta=35^0 \\ r=8ft \end{gathered}$

The formula for arc length is;

$\begin{gathered} A=\frac{\theta}{360}\times2\pi r \\ \\ \Rightarrow A=\frac{35}{360}\times2\pi\times8=4.88\text{ feet} \end{gathered}$
