thickness of one plate 3cm therefore thickness of 30 = 90cm
thickness=height
TSA=2*pie*r*(r+h)
=2*22/7*14(14+90)
=88*104
=9152cm sq
volume = pie*r sq*h
=22/7*14*14*90
=44*1260
=55440

Heightof 1 plate =3cm
Height of 30 plates = 30*3 =90
Radius remains same =14
TSA = 2×22/7×r×r×h
2 *22/7 *14 *{90+14}
2*22*2*104
9152 sq cm
Volume of cylinder =22/7*r*r*h
22/7*14*14*90
55440 cm cube
