Answer 1

Penjelasan dengan langkah-langkah:

.

v balok

v = s × s × s

v = 21 × 21 × 21

v = 441 × 21

v = 9.261 cm³

.

v bola

v = 4/3 × π × r³

v = 4/3 × 3,14 × 10,5 × 10,5 × 10,5

v = 4/3 × 3.634,9425

v = 4.846,59 cm³

.

v balok - v bola

= 9.261 - 4.846,59

= 4.414,41 cm³

Answer 2

Penjelasan dengan langkah-langkah:

• volume balok

v = s × s × s

v = 21 × 21 × 21

v = 441 × 21

v = 9.261

• v. bola

v = 4/3 × π × r³

v = 4/3 × 3,14 × 10,5 × 10,5 × 10,5

v = 4/3 × 3,14 × 1,157.625

v = 4.486,59

• Luas gabungan

= v. balok - v. bola

= 9.261 - 4.486,59

= 4.414,41
