top and bottom have area πr^2 = 196π
sides have area 2πrh = 980π
total: 1176π
A cylindrical vessel without a lid is made from a sheet of metal . Find the area of the metal required if the length of the vessel is 35cm and its diameter is 28cm ????

oops. gotta add another 196π since we have top and bottom.
the length of the vessel h=35 cm
diameter = 28 cm
, therefore the radius of the cylinderical vessels r= 28/2=14cm
the surface area without lid = 2Rrh +Rrsqure
2*22/7*14+22/7*14*14
3080+616
3696 cm
diameter = 28 cm
, therefore the radius of the cylinderical vessels r= 28/2=14cm
the surface area without lid = 2Rrh +Rrsqure
2*22/7*14+22/7*14*14
3080+616
3696 cm
