Tolong bantu kerjakan soal dibawah ini dengan benar​

Answer 1

Jawaban:

b

Penjelasan dengan langkah-langkah:

v tabung = 9.240 liter

d = 28 dm

r = 1/2 x d

r = 1/2 x 28

r = 14 dm

t2 = 6 dm

• cari tinggi total

v = π x r² x t

9.240 = 22/7 x 14 x 14 x t

9.240 = 616 t

t = 9.240 : 616

t = 15 dm

• tinggi yg terisi

= 15 - 6

= 9 dm

• volume yg terisi

= π x r² x t

= 22/7 x 14 x 14 x 9

= 616 x 9

= 5.544 dm³

Answer 2

D = r × 2

r = d/2

r = 28/2

r = 14 cm

V = πr²t

9.240 = 22/7 × 14 × 14 × t

t = 9.240 ÷ 22/7 × 14 × 14

t = 9.240 ÷ 22 × 2 × 14

t = 9.240 ÷ 44 × 14

t = 9.240 ÷ 616

t = 15 dm

tinggi air yang terisi

15 - 6 = 9 dm

Volume air dalam drum

V = πr²t

V = 22/7 × 14 × 14 × 9

V = 22 × 2 × 14 × 9

V = 44 × 14 × 9

V = 616 × 9

V = 5.544 dm³

5.544 dm³ = 5.544 liter (B.)
