tolong jawab no. 4 dan 5 ya

Kelas 6 Matematika
Bab Luas dan Volume

4] r = d/2
r = 7/2
r = 3,5 dm

t = 1,4 m
t = 14 dm

Volume seluruh minyak tanah
= 4 x π x r x r x t
= 4 x 22/7 x 3,5 x 3,5 x 14
= 2.156 liter

5] Volume air
= 2/5 x p x l x t
= 2/5 x 65 x 60 x 25
= 39.000 cm^3

4.

V = 4 × π r^2 t
V = 4 × 22/7 × 3,5 × 3,5 × 14
V = 4 × 539
V = 2.156 l ✓

5.

V = 2/5 × p × t × l
V = 2/5 × 65 × 25 × 60
V = 2/5 × 97.500
V = 39.000 cm3 ✓
