Question : 28

The can is actually cylindrical, so the volume will be :

[tex]\pi {r}^{2} h[/tex]

where,

  • r = radius = 8/2 = 4 cm

  • h = height = 30 cm

so,

  • [tex]3.14 \times 4 \times 4 \times 30[/tex]

  • [tex]1507.2 \: \: cm {}^{3} [/tex]

Question : 29

Let's find the surface area of can with label :

  • [tex]2\pi rh[/tex]

  • [tex]2 \times 3.14 \times 4 \times 30[/tex]

  • [tex]753.6 \: \: {cm}^{2} [/tex]

Question 30 :

Surface area of entire can ~

  • [tex]2\pi r(r + h)[/tex]

  • [tex]2 \times 3.14 \times 4(4 + 30)[/tex]

  • [tex]25.12 \times 34[/tex]

  • [tex]854 .08\: \: cm {}^{2} [/tex]
