Answer:
the loop is going by 4
Step-by-step explanation:
The top two answers are equivalent, while the bottom one is not. You would use distributive property in the parentheses. If both expressions are the same, they are equivalent
First, find the fraction of the circumference represented by central angle 7pi/8:
7pi/8
--------
2pi
Then find the circumference; it is C = 2 pi r, or 2pi(6), or 12 pi units
Then the arc length is 7pi/8 7
-------- * 12 pi = -------- units, or 21/4 units, or 5 1/4 units.
2pi 16 pi
Correct, c and e. they are the only ones that make sense
