An ideal gas has undergone through the cyclic process as shown in the figure. Work done by the gas in the entire cycle is ______ $\times 10^{-1} \mathrm{~J}$.
(Take $\pi=3.14$)

Step-by-step solution

Area of circle, $\mathrm{W}=\frac{\pi}{4} \mathrm{~d}_1 \mathrm{~d}_2$
$\mathrm{W}=\frac{\pi}{4}(500-300) \times 10^3(350-150) \times 10^{-6}$
W = 31.4 Joule
$\mathrm{W}=314 \times 10^{-1} \mathrm{Joule}$
