Answer:
The linear speed is ![1,130.4\frac{ft}{min}](https://tex.z-dn.net/?f=1%2C130.4%5Cfrac%7Bft%7D%7Bmin%7D)
Step-by-step explanation:
step 1
Find the circumference of the circle
The circumference is equal to
![C=2\pi r](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r)
we have
![r=18\ ft](https://tex.z-dn.net/?f=r%3D18%5C%20ft)
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
substitute
![C=2(3.14)(18)](https://tex.z-dn.net/?f=C%3D2%283.14%29%2818%29)
![C=113.04\ ft](https://tex.z-dn.net/?f=C%3D113.04%5C%20ft)
step 2
Find the linear speed in feet per minute
we know that
The wheel is rotating at 10 revolutions per minute
Convert revolutions to feet
Remember that
One revolution is equal to the circumference of the circle
so
10 revolutions is equal to
![(10)113.04=1,130.4\ ft](https://tex.z-dn.net/?f=%2810%29113.04%3D1%2C130.4%5C%20ft)
therefore
The linear speed is ![1,130.4\frac{ft}{min}](https://tex.z-dn.net/?f=1%2C130.4%5Cfrac%7Bft%7D%7Bmin%7D)
