Enough of these logs.
A \( Logarithmic \space Log \) has radius \( \phi (2^n) \), where n is a positive integer from 1-10. Assume the log is a cylinder. The height of all the logs is a constant 10. The volume of the log when n=3 is \( a \pi \) where a is a positive integer. Find a.
Edit: Changed length to radius
