Question

Help with Algebra 2 question. 2) Angle of 2.45 radians forms a arc of 10ft . What is the radius of circle?

Answer 1

The arc length is given by:

`s=r\theta`

In this case the arc length is 10 ft and the angle is 2.45 radians, plugging the values and solving for r we have:

`\begin{gathered} 10=2.45r \\ r=(10)/(2.45) \\ r=4.08 \end{gathered}`

Therefore, the radius of the circle is 4.08
