tolong di bantu dong kak yg no 7

MAPEL = MATEMATIKA
KELAS = 9
BAB = BRSL

diketahui =
diameter = 6cm maka r = 3cm
tinggi tabung = 10cm
tinggi kerucut = 4cm

ditanya =
V. gabungan belahan bola,kerucut & tabung?

V. belahan bola = 2/3πr³
= 2/3 × 3,14 × 3 × 3 × 3
= 2 × 3,14 × 3 × 3
= 56,52 cm³

V. tabung = πr²t
= 3,14 × 3 × 3 × 10
= 282,6 cm³

V. kerucut = ⅓πr²t
= ⅓ × 3,14 × 3 × 3 × 4
= 3,14 × 3 × 4
= 37,68 cm³

V. gabungan
= 56,52 + 282,6 + 37,68
= 376,8 cm³

semoga membantu
