Answer 1

VOLUME TABUNG

πr² × t

3,14 × 12² × 15

3,14 × 144 × 15

3,14 × 2160

6782,4 Satuan Volume

_______________

Luas Permukaan

2πr ( r + t )

2 × 3,14 × 12 ( 12 + 15 )

6,28 × 12 ( 27 )

75,36( 27 )

2.034,72 Satuan Luas Permukaan

_______________

DIAMETER TABUNG

2 × jari - jari

2 × 12

24 Satuan Diameter

Answer 2

• Volume

V = π × r² × t

V = 3,14 × 12² × 15

V = 3,14 × 12 × 12 × 15

V = 3,14 × 144 × 15

V = 3,14 × 2.160

V = 6.782,4 satuan volume

• Luas Permukaan

Lp = 2 × π × r × ( r + t )

Lp = 2 × 3,14 × 12 × ( 12 + 15 )

Lp = 2 × 3,14 × 12 × 27

Lp = 2 × 3,14 × 324

Lp = 2 × 1.017,36

Lp = 2.034,72 satuan luas

• Diameter

d = r × 2

d = 12 × 2

d = 24 satuan panjang
