Question

Find the length of the arc.arc circle 3A. 8π ftB. 32π ftC. 64π ftD. 361π12 ft

Answer 1

Given the circle:

The length, L of the arc is;

`\begin{gathered} L=(\theta)/(360)*2\pi r \\ \\ \theta=90^o,r=16ft \end{gathered}`

Thus;

`\begin{gathered} L=(90)/(360)*2\pi(16) \\ \\ L=8\pi ft \end{gathered}`
`\begin{gathered} L=(90)/(360)*2\pi(16) \\ \\ L=8\pi ft \end{gathered}`
