Answer: 28.28 m²

Step-by-step explanation:

Radius of cylinder- 1.5 m (Given)

Height- 3 m (Given)

To find the metal sheet required, we must find the curved surface area of cylinder that has to be covered.

CSA of cylinder = 2*π*R*H

2*22/7 * 1.5 * 3

= 28.28 m²

Total surface are of cylinder =2×pie×r (h+r)
=2×22/7 ×1.5 (3+1.5)
42.43m^2
