What is the approximate length of arc s on the circle below? Use 3.14 for pi . Round
evablogger [386]

Answer:

6.3

Step-by-step explanation:

Arc length is circumference

C = 2 * pi *r

We are finding a fraction of the total arc length

A circle is 360 degrees

45 degrees  / 360 degrees = 1/8

Find the total arc length and multiply by the fraction of the circle

arc length = 2 * pi * r * 1/8

                  = 2 * 3.14 * 8 * 1/8

                  =6.28

Rounding to the nearest tenth

masya89 [10]

Answer:

Any number above 85.6

Step-by-step explanation:

To calculate the mean you add all of the scores together then divide by how many scores you added

So in this case you would add 84 + 72 + 90 + 87 + 95 = 428

Then you would Divide 428 by five because you are adding 5 numbers

428/5 = 85.6

It says the score increased so as long as then score is greater than 85.6 it is an option.
