Question

Use the formula s=rwt to find the value of the missing variable. S= pi/11 m, r=5 m, t= 8 sec

Answer 1

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
