Need Help ASAP

3) A $57??\mathrm{F}$ capacitor is charged until the voltage measured between the two plates reaches $180\mathrm{V}$. The charging battery is then removed and a slab of some dielectric material ( $?=3.5$ ), is inserted between the plates. Find (a) the capacitance, (b) the plate charge, (c) the voltage between the plates, (d) the stored energy in the capacitor without the dielectric, and (e) the stored energy in the capacitor with the dielectric $\begin{array}{l}{m}_e=9.11\times 10^{?31}\mathrm{kg}\\ {?}_0=8.85\times 10^{?12}\mathrm{F}/\mathrm{m}\\ e=1.6\times 10^{?19}\mathrm{C}\end{array}$
