Answer 2

Radius of the cylinder = 10 cm
Height of the cylinder = 14 cm
 Total surface area of the vessel in the shape of a cylinder open at the top = 2 x [CSA of the cylinder + Area of the base].
= 2 x [2πrh + πr2]
= 2 x [(2 x 3.14 x 14) + (3.14 x 10 x 10)]
= 2 x [87.92 + 314]
= 2 x [401.92]
= 803.84 cm2.
