tolong bantu jawab , no ngasal
π = 22/7(jika kelipatan 7) atau 3,14(bukan kelipatan 7)
1. V = πr² x t
= 22/7 x 7 x 7 x 15
= 2.310 cm³
2. V = πr² x t
= 3,14 x 5 x 5 x 12
= 942 cm³
3. V = πr² x t
= 22/7 x 14 x 14 x 20
= 12.320 cm³
4. V = πr² x t
= 3,14 x 6 x 6 x 16
= 1.808,64 cm³
5. V = πr² x t
= 22/7 x 14 x 14 x 24
= 14.784 cm²
