Question

Someone solve this please

Answer 1

Answer: 13.1

Explanation:

Arc length is angle of given section divided by 360 multiply all of this by the circumference. A is the angle, b is the radius d is the circumference. X is the arc length.

(letters shown have no correlation with the answer choices)

`a=125\\b=6\\d\ =\ \left(2b\right)\cdot3.14\\x=\left((a)/(360)\right)\cdot d`

This makes the arc length equal to 13.0833333333, which you can round up to be 13.1.

Even if you leave pi as what the Desmos Graphing Calculator simplifies it to, it still gives you the answer 13.08996939, which can be rounded up to 13.1.

Although you did not ask for this further information, the arc measure is equal to the center angle that corresponds to the arc, meaning the arc measure is equal to 125°, regardless what the radius or circumference is.
