Tentukan volume gabungan ny? ​

Jawab:

1.197,1875cm³

Penjelasan dengan langkah-langkah:

Volume Gabungan = Volume Balok + Volume 1/2 tabung

Volume balok = 15 × 5 × 14

= 1.050

Volume 1/2 tabung :

1/2 × π × r²× t

1/2 × 3,14 × 2,5 × 2,5 × 15

= 147,1875

Maka Volume Gabungan = 1.050 + 147,1875

= 1.197,1875cm³

V setengah tabung :
V = 1/2 × π × r² × t
V = 1/2 × 3,14 × (5 ÷ 2)² × 15
V = 1/2 × 3,14 × 2,5² × 15
V = 1/2 × 3,14 × 6,25 × 15
V = 294,375/2
V = 147,1875 cm³

V balok :
V = p × l × t
V = 15 cm × 5 cm × 14 cm
V = 75 cm² × 14 cm
V = 1.050 cm³

V gabungan :
= V setengah tabung + V balok
= 147,1875 cm³ + 1.050 cm³
= 1.197,1875 cm³
