Jawab:
Diketahui:
t tabung 12 cm
t kerucut = 21 - 12 = 9 cm
d = 14 cm ⇒ r = 7 cm
Ditanya:
Volume
V tabung + V Kerucut
= [tex]\pi[/tex] x [tex]r^{2}[/tex] x t + [tex]\frac{1}{3}[/tex] x [tex]\pi[/tex] x [tex]r^{2}[/tex] x t
= [tex]\frac{22}{7}[/tex] x 7 x 7 x 12 + [tex]\frac{1}{3}[/tex] x [tex]\frac{22}{7}[/tex] x 7 x 7 x9
= 1.848 + 462
= 2.310 [tex]cm^{3}[/tex]
