----A man leans down on a cane with a vertical force of 110.00N. The narrowest part of the cane has a radius of 1.15cm. What is the maximum compressive stress in the cane?----

For this problem I thought I needed to calculate stress, which is P/A . Pressure is the Force/Area...so I did 110N / Pi 0.0115^2 . And then I divided that answer to get the stress, but it was wrong. Can anyone help me figure out what I did wrong? Thanks :)

Stress is not P/A, it is F/A.

(Note : Stress is a tensor, whose elements are determined from the components of force and area vectors, while pressure is a scalar.)
