Answer 2

242 sq.m. of metal sheet is required to make the tank

Step-by-step explanation:

Radius of tank = 3.5 m

Height of tank = 7.5 m

Total surface area of cylindrical tank = $2 \pi r h +2 \pi r^2$

Total surface area of cylindrical tank = $2 \times \frac{22}{7} \times 3.5 \times 7.5 + 2 \times \frac{22}{7} \times 3.5^2=242 m^2$

Hence 242 sq.m. of metal sheet is required to make the tank
