Formulas:
Area poligono regular.
[tex]Area=\frac{p*a}{2}[/tex]
[tex]p=perimetro[/tex]
[tex]a=apotema[/tex]
Area circulo.
[tex]Area = \pi r^2[/tex]
[tex]r=radio[/tex]
Area triangulo.
[tex]Area=\frac{b*a}{2}[/tex]
[tex]b=base[/tex]
[tex]a=altura[/tex]
Volumen prisma.
[tex]Volumen=A_b *a[/tex]
[tex]A_b = Area \;base[/tex]
Respuesta:
A)
[tex]P_b=6*2cm=12cm[/tex]
[tex]A_b=\frac{12cm*1cm}{2} =\frac{12cm^2}{2}=6cm^2[/tex]
[tex]Volumen=6cm^2*10cm=60cm^3[/tex]
B)
[tex]A_b=\frac{3cm*2cm}{2}=\frac{6cm^2}{2}=3cm^2[/tex]
[tex]Volumen=3cm^2*10cm=30cm^2[/tex]
C)
[tex]A_b=\pi * (4m)^2=\pi16m^2[/tex]
[tex]Volumen=\pi 16m^2*15.8m=\pi 252.8m^3 \approx 793.792 m^3[/tex]
D)
[tex]P_b=5*4cm=20cm[/tex]
[tex]A_b=\frac{20cm*3cm}{2}=\frac{60cm^2}{2}=30cm^2[/tex]
[tex]Volumen=30cm^2*7cm=210cm^3[/tex]
E)
[tex]A_b=\pi * (25cm)^2=\pi 625cm^2[/tex]
[tex]Volumen=\pi 625cm^2*215cm=\pi 134375cm^3 \approx 421937.5cm^3[/tex]
F)
[tex]A_b=\pi * (2.1mm)^2=\pi 4.41mm^2[/tex]
[tex]Volumen=\pi 4.41mm^2*12.4mm=\pi 54.684mm^3 \approx 171.7mm^3[/tex]
