volume of fodder=1/3pie R^2h= $\frac{1}{3} *\frac{22}{7} * (3.6)^2 *2.1=28.51m^3$

l^2=r^2+h^2

l^2=(2.1)^2+(3.6)^2

l^2=4.441+12.96=17.37

l= $\sqrt{17.37}$ =4.17m

minimum area of polythene to cover fodder=pieRl= $\frac{22}{7} *3.6*4.17=47.18m^2$

the volume of fodder is 28.51m^3 and minimum area of polythene to cover fodder in the rainy seasonv47.18m^3
