Question : 28
The can is actually cylindrical, so the volume will be :
[tex]\pi {r}^{2} h[/tex]
where,
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 \times 3.14 \times 4 \times 30[/tex]
- [tex]753.6 \: \: {cm}^{2} [/tex]
Question 30 :
Surface area of entire can ~
- [tex]2 \times 3.14 \times 4(4 + 30)[/tex]
- [tex]25.12 \times 34[/tex]
- [tex]854 .08\: \: cm {}^{2} [/tex]
