MAPEL = MATEMATIKA

Jarijari = 7cm
Tinggi kerucut = 10cm

Ditanya = V bangun??

V. Kerucut = ⅓πr²t
= ⅓ × 22/7 × 7 × 7 × 10
= ⅓ × 22 × 7 × 10
= ⅓ × 1540
= 513,33cm³

V. ½ bola = 2/3πr³
= 2/3 × 22/7 × 7 × 7 × 7
= 2/3 × 22 × 7 × 7
= 2/3 × 1078
= 718,67cm³

V.bangun :
= 513,33cm³ + 718,67cm³
= 1232cm³

semoga membantu
