Central= 127 Radius= 7. What is the length of the indicated arc (x)
tia_tia [17]

Given:

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

Required:

Length of an arc x.

Explanation:

Length of an arc is given as,

Length\text{ of an arc =}\frac{\theta}{360}\times2\pi\text{r}

Length of an arc is calculated as,

\begin{gathered} Length\text{ of an arc = }\frac{127}{360}\times2\times3.14\times7 \\ Length\text{ of an arc = 0.3528 }\times2\times3.14\times7 \\ Length\text{ of an arc = 15.5091 mm} \\  \end{gathered}

alexandr402 [8]

Answer: Hi your question is poorly structured I believe your question is <em>construct a pareto chart to show the major problem areas</em>

answer : attached below is the pareto chart.

Step-by-step explanation:

<u>       Rearranged table starting from highest frequency </u>

The type of Nonconformity                             Frequency      Percentage

     Heel separation                                               92                   40.89

     sole penetration                                              60                     26.67

       Sole separation                                              36                     16

       Other                                                               16                      7.11

      Lace breakage                                                13                       5.8

     Eyelet failure                                                      8                      3.5

   

Total = 36 + 13 + 92 + 8 + 60 + 16 = 225

Next step : determine the percentages of the various Nonconformity

sole separation = 36 / 225 ) * 100 = 16%

lace breakage = ( 13/225 ) * 100 = 5.8% = 6%

Heel separation = ( 92/225 ) * 100 = 40.89% = 41%

Eyelet Failure = ( 8 /225 ) * 100 = 3.5% = 4%

sole penetration = ( 60 / 225 ) * 100 = 26.67% = 27%

other = ( 16 / 225 ) * 100 = 7.11% = 7%

Next plot the Two columns using excel to show the Pareto chart attached below is a screen shot of the plot
