For a circular parallel-plate capacitor whose radius is 0.1m, and which the separation between the plates is 2mm, what is the capacitance of this capacitor?

1.) I created my diagram.

2.) I used C = E0*A/d

C = (8.85*10^-12 C^2/N*m^2) (pi * 0.1^2) / .002m

C = 1.39*10^-10

Is this correct. Thank you for the help.
