21. v.kerucut= 1/3x L.alas x T
= 1/3 x (pi x r x r) x T
= 1/3 x (22/7 x 14 x 14) x 22
= 1/3 x 616 x 22 = 4517,33 cm^3
v.tabung= L. alas x t
= (pi x r x r) x t
= (22/7 x 14x 14) x 20
= 12.320 cm^3
v. gabungan= v.kericut+v.tabung+v.tabung
= 4.517,33+12.230=12.230
=29157,33 cm^3 jawaban nya yang (d)
22. v.tabung= l.alas x t
= (pi x r x r) x t
= (3,14 x 5 x 5) x 36
=78,5 x 36
= 2.826 cm^3
v.balok= p x l x t
= 25 x 10 x 15
= 3.750 cm^3
v. gabungan= v.tabung+v.balok
=2.826+3.750
=6.576 jawaban nya yang (b)
