volume bangun tersebut adalah

MAPEL = MATEMATIKA
KELAS = 9
BAB = BRSL

Diketahui =
Diameter = 10cm, maka r = 5cm
Tinggi tabung = 8cm
Garis pelukis = 13cm

Ditanya = V.gabungan??

- V. Tabung = πr²t
= 3,14 × 5 × 5 × 8
= 3,14 × 200
= 628cm³

- mencari tinggi kerucut
T = √s² - r²
T = √13² - 5²
T = √169 - 25
T = √144
T = 12cm

- V. Kerucut = ⅓πr²t
= ⅓ × 3,14 × 5 × 5 × 12
= 3,14 × 5 × 5 × 4
= 3,14 × 100
= 314cm³

V.gabungan :
= 268cm³ + 314cm³
= 582cm³

Semoga membantu

Volume tabung :
= 3,14 ×5 ×5 × 8
= 628

volume kerucut :
= 1/3 × 3,14 × 5 ×5 × 12
= 3, 14 × 5 × 5 × 4
= 3, 14 × 100
= 314

= 628 + 314
= 942
