Hello mate ,
Your answer:-
__________________________
Height of closed cylindrical tank ,h=1 m
Base diameter of cylindrical tank =d=140 cm
=140/100
=1.4 m
⇒ Radius of cylindrical tank ,r
=d/2
=1.4/2
=0.7 m
Total surface area of cylindrical tank
=2πr(r+h)=2×22/7×0.7(0.7+1)
=2×22/7×0.7×1.7
=7.48 m^2
I hope, this will help you.☺
Thank you______❤
