Step-by-step explanation:
Given:
Height of the cylindrical tank = 1.4m
Radius of the base = 56cm
= 56/100m = 0.56m
Metal sheet required to make the cylindrical tank = 2πr(r + h)
= 2 × 22/7 × 0.56(0.56 + 1.4)
= 2 × 22/7 × 0.08(1.96)
= 35.2 × 1.96
= 6.8992 square metres.
Answer = 6.8992 square metres.
