Which best describes how to find the length of an arc in a circle?
2 answers:
Answer:
<h2>A. Divide the arc's degree measure by 360°, then multiply by the circumference of the circle.</h2>Step-by-step explanation:
The first choice describes the right way to find the length of an arc in a circle.
The length of an arc is defined as
Where represents the circumference of the circle and
represents the arc's degree measure.
So, as you can observe through this formula, we need to divide the arc's degree measure by 360°, and then multiply this result with the circumference of the circle, that's the right way based on the definition of arc length.
Therefore, the right answer is A.

We want to find a graph that represents Noah's average speed.
We define the average speed as the quotient between the distance moved and the time it takes to move that distance, then in this case we will have:
s = 12ft/6s = 2ft/s
Then we can define a linear equation:
y = (2ft/s)*x
As the distance that Noah travels in x seconds.
The graph of the given linear function can be seen below, and that is the graph with the slope that best represents Noah's average speed.
