tolong bantuannya jawaban no 3 sampai 4 beserta caranya

3a
V = r³
V = 4³
V = 64 cm³

3b
V = r³
64 = r³
r =
[tex] \sqrt[3]{64} [/tex]
r = 4 cm

4a
V = L alas × t
V = 60 × 15
V = 900 cm³

4b
V = L alas × t
V = 8² × 12
V = 64 × 12
V = 768 cm³

4c
V = L alas × t
V = (½ × 9 × 12) × 10
V = 54 × 10
V = 540 cm³

semoga membantu :)
