Question

Find the radius of a circle whose arc length is 55 m and its central angle measure if 5 radians

Answer 1

Explanation:

To solve this question, we can use the formula
`S=\theta r`, where
`S` is the arc length,
`\theta` is the central angle of the sector in radians, and
`r` is the radius.

In this situation, we know that
`S=55` and
`\theta=5`

This means that
`55=5r \longrightarrow \boxed{r=11}`
