Answer :

Radius of each circular plate = 10.5 cm

Thickness of each plate = 1.6 cm

25 plates are placed one above the other to form a solid circular cylinder

∴ height of the cylinder formed, h = 25 × 1.6 cm = 40cm

Total curved surface area of the cylinder = 2πrh

= 2640 cm^{2}

Volume of cylinder = π r^{2} h

= π (10.5)^{2} × 40

= 13860 cm^{3}
