Answer:
![90\pi\text{ ft/s}\approx282.74\text{ ft/s}](https://tex.z-dn.net/?f=90%5Cpi%5Ctext%7B%20ft%2Fs%7D%5Capprox282.74%5Ctext%7B%20ft%2Fs%7D)
Step-by-step explanation:
Refer to physics equation
, where
is angular velocity.
Angular velocity's SI unit is rad/s. Convert rev/min to rad/s:
![\displaystyle 5\text{ rev/min}=5\cdot \frac{1}{60}\cdot 2\pi\approx 0.524\text{ rad/s}](https://tex.z-dn.net/?f=%5Cdisplaystyle%205%5Ctext%7B%20rev%2Fmin%7D%3D5%5Ccdot%20%5Cfrac%7B1%7D%7B60%7D%5Ccdot%202%5Cpi%5Capprox%200.524%5Ctext%7B%20rad%2Fs%7D)
Now substitute
and
into
:
![\displaystyle v=\frac{1\pi}{6}\cdot 9=\frac{3}{2}\pi\text{ ft/s}=\boxed{90\pi\text{ ft/s}}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20v%3D%5Cfrac%7B1%5Cpi%7D%7B6%7D%5Ccdot%209%3D%5Cfrac%7B3%7D%7B2%7D%5Cpi%5Ctext%7B%20ft%2Fs%7D%3D%5Cboxed%7B90%5Cpi%5Ctext%7B%20ft%2Fs%7D%7D)

The decimal equivalent of 45⁰ 32’ 55” is 45.55⁰
<h3>Converting degrees into decimal</h3>
The given degree is:
45⁰ 32' 55''
This can be converted to decimal as shown below
![45+\frac{32}{60} +\frac{55}{3600}](https://tex.z-dn.net/?f=45%2B%5Cfrac%7B32%7D%7B60%7D%20%2B%5Cfrac%7B55%7D%7B3600%7D)
This can be simplified further as:
![45^o32'55'' = 45+0.53+0.0153\\\\45^o32'55'' = 45.55^0](https://tex.z-dn.net/?f=45%5Eo32%2755%27%27%20%3D%2045%2B0.53%2B0.0153%5C%5C%5C%5C45%5Eo32%2755%27%27%20%3D%2045.55%5E0)
Therefore, the decimal equivalent of 45⁰ 32’ 55” is 45.55⁰
