MOHON PAKE CARA! JAWAB YA

Diketahui :
- Jari - Jari = 7 cm
- Tinggi = 10 cm

Ditanya : Volume Bangun = ....?

Penyelesaian :
- Volume Tabung :
V = π × r × r × t
V = 22/7 × 7 × 7 × 10
V = 22 × 7 × 10
V = 154 × 10
V = 1.540 cm³

- Volume Setengah Bola :
V = 2/3 × π × r × r × r
V = 2/3 × 22/7 × 7 × 7 × 7
V = 2/3 × 22 × 7 × 7
V = 2/3 × 154 × 7
V = 2/3 × 1.078
V = 718⅔ cm³

- Volume Bangun :
V = 1.540 cm³ + 718⅔ cm³
V = 2.258⅔ cm³

Jawaban : A. 2.258,67 cm³

Maaf Kalau Salah

V = V.tabung + V.1/2bola
= (Phi.r2.t )+ (1/2.4/3.Phi.r3)
= (22/7 x 7 x 7 x 10) + (1/2 x 4/3 x 22/7x7x7x7)
= 1540 + 718,67
= 2258,67 (A)
