note : jawab dengan penjelasan
Diketahui:
- r = 70 cm
- t = 90 cm
- 75% = ¾
- - - - -
Pertama, cari volume drum.
V = π × r × r × t
V = 22/7 × 70 × 70 × 90 cm³
V = 22 × 70/7 × 70 × 90 cm³
V = 22 × 10 × 70 × 90 cm³
V = 220 × 70 × 90 cm³
V = 15.400 × 90 cm³
V = 1.386.000 cm³
V = 1.386 dm³
V = 1.386 liter
- - - - -
Kedua, cari volume 75% drum
= 75% × V. drum
= 75% × 1.386 liter
= ¾ × 1.386 liter
= 4.158 ÷ 4 liter
= 1.039,5 liter
- - - - -
Ketiga, cari volume yg diperlukan agar penuh.
= V. drum - V. 75% drum
= 1.386 liter - 1.039,5 liter
= 346,5 liter
