kak tolong bantu, pakai cara ya kak

volume tabung = luas alas × tinggi tabung
volume tabung = ( π.r.r) × t
1) (22/7 × 7 ×7) ×15
154 × 15
= 2.310 cm³

2) (3,14 × 10 × 10 ) × 18
314 × 18
= 5,652 cm³

3). (22/7 ×14 × 14 ) × 30
616 × 30
= 18,480 cm³

1)V= πr²t
=22/7×7×7×15
=2310 cm³

2) V= πr²t
= 3,14×10×10×18
= 5652 cm³

3) V = πr²t
= 22/7×14×14×30
= 18480 cm³
