  a)

  Al= Pi*r*g

  g^2=r^2+h^2

  g^2=(6*6)+(8*8)

  g^2=36+64

  g=V100

  g=10

  Al= Pi*r*g

  Al=3,14*6*10

  Al=188,4 cm^2

  b)

  At=Al + Ab

  Ab=pi*r^2

  Ab=3,14*36

  Ab=113,04 cm^2

  At=Al + Ab

  At=188,4 + 113,04

  At=301,44 cm^2

  c)

  V=(Ab*h)/3

  V=(113,04*8)/3

  V=904,32/3

  V=301,44 cm^3
