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
5 kilometers in meters are 5000, 1 kilometer is 100 meters
Answer:
Er you just multiply by 9.
Step-by-step explanation:
1*9 = 9
3*9=27
1*9=9
27*9=243
-16 + 24 = 8
Because 24 - 16 = 8
