In a cyclic process so the Net change in internal energy of the system will be zero.
i.e,
                          \mathrm{\Delta v=0}

from Exist law of thermodynamic 

                    \begin{aligned} \Delta \mathrm{Q} &\mathrm{ =\Delta U+\Delta W }\\ \therefore \Delta Q &\mathrm{ =\Delta W} \end{aligned}

\Delta \omega= is the area of stander Region

\begin{aligned} \text { cycle }=& \text { waycle }= \\ &\mathrm{ =\pi \times 25 \times 10 \quad \quad \mathrm{kpa}-\mathrm{CC} }\\ &\mathrm{ =\pi(25)(10) \times 10^3 \times 10^{-6} }\\ &\mathrm{ =.250 \mathrm{~\pi J} }\\ \end{aligned}
