Answer 1

Jawaban:

A. Berapakah liter volume air dalam bak penampungan?

Jawaban:

Volume air = πr'²t'

= 3,14 × 50 × 50 × 50

= 392.500 cm³

= 392,5 dm³

= 392,5 Liter

B. Berapa kali ember harus di isi untuk memindahkan semua air dalam bak penampungan?

Jawaban:

volume ember = πr"²t"

= 3,14 × 10 × 10 × 35

= 10.990 cm³

= 10,99 dm³

= 10,99 Liter

Answer 2

Penjelasan dengan langkah-langkah:

BANGUN RUANG LENGKUNG

• T A B U N G

Bak Air,

d = 1 m = 10 dm

r = 5 dm

t = 1,2 m = 12 dm

t.air = 50 cm = 5 dm

π = 3,14

Ember,

d = 20 cm → r = 10 cm

t = 35 cm

π = 22/7

Volume air = πr²t.air

Volume air = 3,14 × 5² × 5

Volume air = 3,14 × 125

Volume air = 392,5 liter

Volume air = 392.500 cm³

Volume Ember = πr²t

Volume Ember = 22/7 × 10² × 35

Volume Ember = 22 × 100 × 35/7

Volume Ember = 2.200 × 5

Volume Ember = 11.000 cm³

a. Volume air di bak penampungan = 392,5 liter

b. Ember harus diisi sebanyak

= Volume air

Volume ember

= 392.500

11.000

= 35,7 kali

≈ 36 kali
