Question 930497
f I have a pvc pipe that is 3feet tall and has.
 Diameter 4 inches how many pennies can I fit in the pvc pipe
:
Here is how you can do this. Draw a 4" diameter circle on a piece of paper. See how many pennies  fit inside this 4" circle
The thickness of a penny is 1.55 mm
 3' is about 914 mm
therefore, 914/1.55 ~ 590 layers of pennies,
multiply this by the no. of pennies you can put in a 4" circle
