Answer 1

Jawab:

1. 1.570 cm³

2. 3.080 cm³

Penjelasan dengan langkah-langkah:

⇒ Rumus Volume Tabung = πr² t

1. Jari - jari = 1/2 × diameter

Jari - jari = 1/2 × 10 = 5 cm

Tinggi = 20 cm

≅V. Tabung = 3,14 × 5² × 20

V. Tabung = 3,14 × 25 × 20

V. Tabung = 1.570 cm³

2. Jari - jari = 7 cm

Tinggi = 20 cm

≅ V. Tabung = × 7² × 20

V. Tabung = × 49 × 20

V. Tabung = 22 × 7 × 20

V. Tabung = 3.080 cm³
