thanks yg udah jawab God bless you ​

Answer 1

1.

V = π.r.r.t

V = 3,14.12.12.18

V = 37,68.12.18

V = 452,16.18

V = 8.138,88 cm³

2.

V = π.r.r.t

V = 3,14.15.15.15

V = 3,14.225.15

V = 3,14.3.375

V = 10.597,5 × 4/3

V = 42.390/3

V = 14.130 cm³

Answer 2

Volume Tabung

πr² × t

3,14 × ( 24 ÷ 2 )² × 18

3,14 × 12² × 18

3,14 × 12 × 18

452,16 × 18

3.138,88 cm³

Volume Bola

4/3 × πr³

4/3 × 3,14 × 15³

4/3 × 3,14 × 15 × 15 × 15

4 × 3,14 × 5 × 15 × 15

4 × 3,14 × 75 × 15

12,56 × 1.125

14.130 cm³
