If they are charged to a potential difference of 22 V, what is the charge resident on each plate?

Question

A parallel plate capacitor is made of two circular thin plates of radius 15 cm separated by 2.5 mm of air.

Thanks

First find the net capacitance using the formula
Net capacitance(C) = (eo (area))/d (where eo = 8.85*10^-12 and d is the distance between the plates)

Then, charge resident on each plate will be
Charge (Q) = C*V(potential difference)
