Period =2r /b
assume frequency factor meaning angular frequency "b"
then
2r= 2r/b => b=1
A. sine function whose period 2pi radians
ANSWER
B. 8
EXPLANATION
Volume of wooden crate is
![\frac{1}{27} {ft}^{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B27%7D%20%20%7Bft%7D%5E%7B3%7D%20)
The cubic blocks have side length,
![l = \frac{1}{6} ft](https://tex.z-dn.net/?f=l%20%3D%20%20%5Cfrac%7B1%7D%7B6%7D%20ft)
The volume of each cubic blocks is,
![v = {l}^{3}](https://tex.z-dn.net/?f=v%20%3D%20%20%7Bl%7D%5E%7B3%7D%20)
![= ( \frac{1}{6} )^{3} = \frac{1}{216}](https://tex.z-dn.net/?f=%20%3D%20%20%28%20%5Cfrac%7B1%7D%7B6%7D%20%29%5E%7B3%7D%20%20%3D%20%20%5Cfrac%7B1%7D%7B216%7D%20)
Number of blocks that can go into the crate is,
![= \frac{ \frac{1}{27} }{ \frac{1}{216} }](https://tex.z-dn.net/?f=%20%20%3D%20%5Cfrac%7B%20%5Cfrac%7B1%7D%7B27%7D%20%7D%7B%20%5Cfrac%7B1%7D%7B216%7D%20%7D%20)
![= \frac{1}{27} \times \frac{216}{1}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B1%7D%7B27%7D%20%20%5Ctimes%20%20%5Cfrac%7B216%7D%7B1%7D%20)
![= 8 \: blocks](https://tex.z-dn.net/?f=%20%3D%208%20%5C%3A%20blocks)
