In a circle with a radius of 12.6 ft and an arc is intercepted by a central angle of 2 pi over seven radians what is the arc length

❤️Hello!❤️ The answer is 11.31 feet                                                                    arc length = radius * central angle (in radians)

arc length = 12.6 * 2*PI/7

arc length = 25.2 * PI/7  

arc length = 11.31 feet ☯️Hope this helps!☯️  ↪️ Autumn ↩️

11.31 ft is the arc length.

Step-by-step explanation:

We have given the radius r = 12.6 ft and arc intercept by central angle

Ф = 2π/7.

We have to find the arc length.

We know the formula to find the arc length that is:

L = rФ

Putting the values we get,

 L= 12.6 × 2π/7

L = 25.2 π/7

L = 11.31 ft  is the answer.

11.31 ft is the arc length.

i think it is

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
