tolong bantuuuuuuuuuuuuu
KERUCUT
Diketahui:
r = 10 cm
t = 15 cm
π = 3,14
Penyelesaian:
Rumus Volume Kerucut
= ⅓ × π × r² × t
= ⅓ × (3,14 × 10² × 15)
= ⅓ × (3,14 × 100 × 15)
= ⅓ × 4.710
= 1.570 cm³
½ BOLA
Diketahui:
r = 10 cm
π = 3,14
Penyelesaian:
Rumus Volume ½ Bola
= ½ × 4/3 × π × r³
= ½ × 4/3 × (3,14 × 10³)
= 4/6 × (3,14 × 1000)
= 4/6 × 3.140
= 2.093,33 cm³
VOLUME GABUNGAN
= Volume Kerucut + Volume Bola
= 1.570 cm³ + 2.093,33 cm³
= 3.663.33 cm³
