a.) 3.542 cm³
b.) 3.975 cm³
Penjelasan:
Soal A
→ V kerucut + V tabung
→ (1/3 × π × r² × t) + (π × r² × t)
→ (1/3 × 22/7 × 7 × 7 × 24) + (22/7 × 7 × 7 × 15)
→ (22 × 7 × 8) + (22 × 7 × 15)
→ 1.232 + 2.310
→ 3.542 cm³
Soal B
→ V limas + V kubus
→ (1/3 × L.alas × t) + (s × s × s)
→ (1/3 × 15 × 15 × 8) + (15 × 15 × 15)
→ 600 + 3.375
→ 3.975 cm³
Jawaban :
B ) 3.542 cm³
C ) 3.975 cm³
Penjelasan dengan langkah-langkah :
Yang B
Diketahui :
Ditanya :
Berapa Volume Gabungan Kerucut & Tabung...?
Jawab :
Volume Kerucut =
V = ⅓ π r² t
V = ⅓ × ²²/₇ × 7 × 24
V = 22 × 56
V = 1.232 cm³
Volume Tabung =
V = π r² t
V = ²²/₇ × 14² × 15
V = 22 × 105
V = 2.310 cm³
V Gabungan =
V1 + V2 = 1.232 + 2.310 = 3.542 cm³
Yang C
Volume Gabungan Kubus & Limas =
Berapa Volume Gabungan Tersebut... ?
Volume Kubus =
V = s³
V = 15³
V = 3.375 cm³
Volume Limas =
V = ⅓ × La × t
V = ⅓ × 15² × 8
V = ⅓ × 1800
V = 600 cm³
Volume Gabungan =
V1 + V2 = 3.375 + 600 = 3.975 cm³
