9 cm 11 cm 20 cm Volume bangun tersebut adalah.... (= = 3,14)
​

Answer 1

Verified answer

Jawaban:

4400cm³

Penjelasan dengan langkah-langkah:

dik: diameter = 20m, t.tabung = 11cm, t.kerucut = 9cm

dit: volume = ?

cara:

V.tabung = 22/7 × (20÷2)² × 11

= 22/7 × 100 × 11

= 3457,14cm³

V.kerucut = 22/7 × (20÷2)² × 9 ÷ 3

= 22/7 × 100 × 9 ÷ 3

= 22/7 × 100 × 3

= 942,85cm³

V.bangun = 942,85+3457,14

= 4399,99cm³

= 4400cm³

kalo bner kasih jwabn tercerdasnya ya

Answer 2

Penyelesaian:

d = 20 cm

r = 10 cm

t selimut tabung = 11 cm

t kerucut = 9 cm

Volume tabung:

• V = πr²t
• V = 3,14 × 10² × 11
• V = 3.454 cm³

Volume kerucut:

• V = ⅓ × πr²t
• V = ⅓ × 3,14 × 10² × 9
• V = ⅓ × 2.826
• V = 942

Volume bangun tsb:

• V = V tabung + V kerucut
• V = 3.454 + 942
• V = 4.396 cm³

Jawaban: 4.396 cm³
