A steel rod is 1/2 inch in diameter and 58 feet long. What is its volume. Use 3.14 round to the nearest tenth

Thank you for the opportunity to help you with your question!

To find the volume of the steel rod, you need to use the equation for a cylinder:

V=(3.14)*(r^2)*(h)       This is V=area of circular base * height of rod

r=radius of circular base

h=height of rod

Before using the equation you need to make sure all the units are the same, in this case, inches.  And calculate the radius from the diameter.

r=(1/2)*d=(1/2)*(1/2)=0.25 inches

h=58 feet * (12 inches / 1 foot) = 696 inches

Now plug into the formula:

V=(3.14)*(0.25^2)*(696)

V=136.59

Volume=136.6 inches^3

Please let me know if you need any clarification. I'm always happy to answer your questions.
