Question

Find the length of the arc. Use 3.14 for it.270°8 cm

Answer 1

The radius of circle is r = 8 cm.

The arc is of angle 270 degree.

The formula for the arc length is,

`l=2\pi r\cdot(\theta)/(360)`

Determine the length of the arc.

`\begin{gathered} l=2\cdot3.14\cdot8\cdot(270)/(360) \\ =37.68 \end{gathered}`

So lenth of the arc is 37.68.
