Ampere's Law and Displacement Current...anybody?

Determine the rate at which the electric field changes between the round plates of a capacitor, 6.0 cm in diameter, if the plates are spaced 1.3 mm apart and the voltage across them is changing at a rate of 120V/s

I found area:

A = 2πr2 = 2 π(.03 m)2

= .006 m

then do I solve for dE/dt ?

Gamma

Why do you need area to find E?
