tolong jwb nomer 21...

d= 6 cm > r= 3 cm
t= 14 cm
Ditanya= V?

V= πr²t
V= 22/7 x 3 x 3 x 14
V= 22 x 3 x 3 x 2
V= 66 x 3 x 2
V= 198 x 2
V= 396 cm³

Yg A jawabannya.

Hopefully this is the best for you, Stay focus and be the best, Buddy :)

Mapel : Matematika
Bab : Bangun Ruang Sisi Lengkung

Diketahui :
- Diameter Tabung = 6 cm
- Jari - Jari Tabung = ½ × 6 cm = 3 cm
- Tinggi Tabung = 14 cm

Ditanya :
- Volume Tabung = .....?

Penyelesaian :
- Volume Tabung :
V = π × r × r × t
V = 22/7 × 3 cm × 3 cm × 14 cm
V = 22 × 9 cm² × 2 cm
V = 22 × 18 cm³
V = 396 cm³

Jawaban : A. 396

Maaf Kalau Salah
