Tolong bantuannya ya kakak kakak, Tolong jangan ngasal ya kakak:D
Penjelasan dengan langkah-langkah:
V = (1/3)πr²t + (2/3).π.r³
V = (1/3 × 22/7 × 7 × 7 × 9) + (2/3 × 22/7 × 7 × 7 × 7)
V = (22 × 7 × 3) + (2/3 × 22 × 49)
V = 462 + 718,67
V = 1.180,67 cm³ (C)
Volume Kerucut
- ⅓ × πr² × t
- ⅓ × 22/7 × ( 14 ÷ 2 )² × 9
- 22/7 × 7² × 3
- 22/7 × 7 × 7 × 3
- 22 × 1 × 7 × 3
- 22 × 21
- 462 cm³
Volume ⅔ Bola
- ⅔ × πr³
- ⅔ × 22/7 × ( 14 ÷ 2 )³
- ⅔ × 22/7 × 7³
- ⅔ × 22/7 × 7 × 7 × 7
- ⅔ × 22 × 1 × 7 × 7
- ⅔ × 22 × 49
- ⅔ × 1.078
- 2.156/3
- 718,66 cm³
volume gabungan
- Volume Kerucut + volume ⅔ bola
- 462 + 718,66
- 1.180,66666
- 1.180,67 cm³ ( C )
