Question

Tentukan volume gabungan bangun ruang di bawah ini!​

Answer 1

Penjelasan dengan langkah-langkah:

VbR

= V.Tabung + V.Kerucut

= (πr²t)+(⅓πr²t)

= (22/7×14×14×35) + (⅓×22/7×14×14×15)

= (22×14×14×5) + (22×14×2×5)

= (21560) + (3080)

= 24640 cm³

Answer 2

Verified answer

Jawab:

t kerucut = 15 cm

d tabung = 28 cm ⇒ r tabung dan r kerucut = 14 cm

t tabung = 50 - 15 cm = 35 cm

V gabungan = V kerucut + V tabung

= (1/3 πr² t) + (π r² t)

= (1/3 x 22/7 x 14 x 14 x 15) + (22/7 x 14 x 14 x 35)

= 3.080‬ + 21.560‬

= 24.640‬ cm³
