Answer: D. [tex]\frac{Tv}{2\pi}[/tex]
Step-by-step explanation:
The given formula : [tex]V=\frac{2\pi r}{T}[/tex]
To rearrange the given formula in terms of r, first we need to multiply T on the both sides, we get
[tex]VT=2\pi r[/tex]
In the second step, divide [tex]2\pi [/tex] on both the sides, we get
[tex]r=\frac{VT}{2\pi}[/tex]
Hence , the rearrange formula for r =[tex]\frac{VT}{2\pi}[/tex]
