It is required to make a closed cylindrical tank of height 1m and base diameter 140 cm from a

metal sheet. How many square meters of the sheet are required for the same? Assume π=22/7

Answer:

Let h be the height and r be the radius of a cylindrical tank.

Height of cylindrical tank, h = 1m

Radius = half of diameter = (140/2) cm = 70 cm = 0.7m

Area of sheet required = Total surface are of tank = 2πr(r + h) unit square

[2 \times 22 / 7 \times 0.7(0.7+1)]

= 7.48

Therefore, 7.48 square meters of the sheet are required.
