Jawaban:

c

Penjelasan dengan langkah-langkah:

a. V = V. setengah bola + V. tabung

= (1/2 × 4/3 π r³) + (π r² t)

= (1/2 × 4/3 × 3,14 × 20³) + (3,14 × 20² × 15)

= 50.240 16.746,67 + 18.840

= 35.586,67 cm³

b. V = V. balok besar + V. balok kecil

= (p × l × t) + (p × l × t)

= (21 × 14 × 14) + (21 × 10 × (22-14))

= 4.116 + 1.680

= 5.796 cm³

c. V = V. setengah tabung + V. balok

= (½ × π r² t) + (p × l × t)

= (½ × 22/7 × 7² × 36) + ( 16 × 14 × 36)

= 2.772 + 8.064

= 10.836 cm³

d. V = V. limas segiempat + V. kubus

= (⅓ × luas alas × t) + (s³)

= (⅓ × 15 × 15 × 7) + 15³

= 525 + 3.375

= 3.900 cm³
