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
