tolong dong pppppllllllllliiiiiiissssss

1 ) v tab = πr²t
= 3,14. 12. 12. 18
= 3,14. 144. 18
= 452,16. 18
= 8138,88 m³

2 ) V tab = πr²t
= 3,14. 8.8. 16
= 3,14. 64. 16
= 3215,36 m³

3 ) Luas alas = LO = πr² = 154 cm²
V tab = πr²t
= 154. 24
= 3696 cm³

4 ) tinggi = jari" = 35 cm
V tab = πr²t
= 22/7. 35. 35. 35
= 22. 5. 35. 35
= 134750 cm³

semoga membantu ya ^_°
