Answer:
1. vol. = [tex]\frac{1}{3}[/tex] [tex]a^{2}[/tex]h
= [tex]\frac{1}{3}[/tex] [tex]10^{2}[/tex]×6
= 100 × 6
= 600 ÷ 3
= [tex]200cm^{3}[/tex]
2. vol. = [tex]\frac{1}{3}[/tex]π[tex]r^{2}[/tex]h
= [tex]\frac{1}{3}[/tex] π×[tex]3^{2}[/tex]×10
= π×9×10
= 282.74 ÷ 3
=[tex]94.24cm^{3}[/tex]
3. vol. = π[tex]r^{2}[/tex]h
= π×6²×8
= π×36×8
= [tex]904.77cm^{3}[/tex]
4. vol. = [tex]\frac{1}{3}[/tex]L×W×H
= [tex]\frac{1}{3}[/tex] 12×4×8
= 384 ÷ 3
= 128m³
