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.

Answer:
I'll try my best in explaining the steps.
Considering both signs are greater than and less than sign, its an open circle.
For the first equation, you would have an open circle, basically one that isn't colored in, on 8 on the number line. The arrow would be pointing to the left because the equation is telling us numbers that are less than 8.
For the second equation, you would have an open circle, basically one that isn't colored in, on -1 on the number line. The arrow would be pointing to the right because the equation is telling us numbers that are greater than -1.

Answer:
k = 18
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = 3 when x = 6, that is
3 = ( multiply both sides by 6 )
18 = k
The constant of variation is k = 18
