Answer:

w = π/440

Step-by-step explanation:

The formula is:


s=r\cdot w\cdot t

Then, replacing s = π/11, r = 5 and t by 8, we get:


(\pi)/(11)=5\cdot w\cdot8

So, to solve for w, we first need to multiply 5 by 8:


(\pi)/(11)=40\cdot w

Finally, divide both sides by 40:


\begin{gathered} (\pi)/(11)\cdot(1)/(40)=(40\cdot w)/(40) \\ (\pi)/(440)=w \end{gathered}

So, the missing variable is w = π/440
