Answer:
8.792 m²s
Explanation:
Given the equation:
[tex]v=r\omega t[/tex]
We want to evaluate the value of v for the given variables below:
[tex]\omega=\frac{\pi}{5}m,r=7m,t=2\sec [/tex]
Substitute the values into the formula:
[tex]\begin{gathered} v=7m\times\frac{\pi}{5}m\times2\sec \\ v=7\times\frac{\pi}{5}\times2\times(m\times m\times\sec ) \\ v=\frac{14\pi}{5} \\ v\approx\frac{14\times3.14}{5} \\ v\approx8.792\; m^2s \end{gathered}[/tex]
The value of v is 8.792 m²s.
