Jawaban:

4. 25.624,755 cm³

5. 68.000 cm³

Penjelasan dengan langkah-langkah:

4. Vk = 1/3πr²t

= 1/3 × 3,14 × 4,5 × 4,5 × 12

= 3,14 × 4,5 × 4,5 × 4

= 254,34 cm³

Vb = 1/2 × 4/3 πr³

= 1/2 × 4/3 × 3,14 × 4,5 × 4,5 × 4,5

= 1/2 × 4/3 × 286.1325

= 1/2 × 381.51

= 190.755 cm³

Volume gabungan:

=Vk + Vb

= 254,34 cm³ + 190,755 cm³

= 25.624,755 cm³

5. Vl = 1/3× luas alas × tinggi

= 1/3 × ( 30 × 10) × 25

= 1/3 × 300 × 23

= 100 × 23

= 2.300 cm³

Vb = p × l × t

= 30 × 10 × 15

= 4.500 cm³

Volume gabungan:

=Vl + Vb

= 2.300 + 4.500

= 6.800 cm³
