Given a temperature C in celsius, you can convert it to Fahrenheit by using the formula

In your case C=39, so you have

Answer:
volume of fodder=1/3pie R^2h=
l^2=r^2+h^2
l^2=(2.1)^2+(3.6)^2
l^2=4.441+12.96=17.37
l=
=4.17m
minimum area of polythene to cover fodder=pieRl=
the volume of fodder is
and minimum area of polythene to cover fodder in the rainy seasonv47.18m^3
The first equation equals 13
The second one equals 12
to help you discover the answer better I really think the second one
It’s A bc 228/3 is 76 and the rest of the answers seems like it wouldn’t be the correct answer.(I apologize if I’m wrong)
