Question

Find the area of a tin sheet required to make a cylindrical vessel

Answer 1

Answer:

radius of base=14 cm

Surface area of cylinder=2πrh+2πr²

2πr(r+h)=2x22/7x2(16+14)

30x44x2=2640 cm²

volume of cylinder=πr²h=196x16π=3136π=9856cm³

Answer 2

Answer:

Area of tin sheet required to make a cylindrical vessel = Curved suface area of cylinder+ area of bottom(circle)
