YANG JAWAB AKU KASIH
Jawaban:
1) Diket: EB = 18cm
DE = 20cm
DF = 30dm
L.Alas = 200cm2
Jawab: V.Prisma = L.Alas x Tinggi
= 200×18
= 3.600cm3
2) Jawab: V.Kerucut = 1/3 x π x r2 x t
= 1/3 x 22/7 x 7 x 7 x 12
= 22 x 7 x 4
= 616cm3
3) Diket: d.Tabung = 28cm
r = 14cm
t = 10cm
Jawab: V.Tabung = π x r2 x t
=22/7 x 14 x 14 x 10
=22 x 2 x 14 x 10
=6.160cm3 } D.
4) Jawab: V.Limas = 1/3 x L.Alas x t
= 1/3 x (6×7:2) x 20
= 2 x 7 x 10
= 140cm3 } D.
5) Jawab: V.Kerucut = 1/3 x π x r2 x t
= 1/3 x 22/7 x 7 x 7 x 15
= 22 x 7 x 5
= 770cm3
