What is the minimum uncertainty in the speed of an electron confined to within a lead atom of diameter 350. pm?

We are given the uncertainty in the electron's position ($\Delta x$), which is 350 pm and we know the electron's mass so we can use the Heisenberg Uncertainty equation in order to solve for the uncertainty in the velocity. Just make sure to convert the 350 pm into meters.
