Question

Central= 127 Radius= 7. What is the length of the indicated arc (x)

Answer 1

Given:

`\begin{gathered} \theta\text{ = 127} \\ r\text{ = 7 mm} \end{gathered}`

Required:

Length of an arc x.

Step-by-step explanation:

Length of an arc is given as,

`Length\text{ of an arc =}(\theta)/(360)*2\pi\text{r}`

Length of an arc is calculated as,

`\begin{gathered} Length\text{ of an arc = }(127)/(360)*2*3.14*7 \\ Length\text{ of an arc = 0.3528 }*2*3.14*7 \\ Length\text{ of an arc = 15.5091 mm} \\ \end{gathered}`

Answer:

Thus the value of the length of an arc is 15.5091 mm
