Berapa volume bangun ruang gabungan di atas?
Jawaban:
Penjelasan dengan langkah-langkah:
V l = Volume 1/2 bola
= 1/2 × 4/3 × π × r³
= 1/2 × 4/3 × 3,14 × 10 cm × 10 cm
= 2/3 × 3140 cm³
= 2093,33 cm³
V ll = Volume Kerucut
= 1/3 × π × r² × t
= 1/3 × 3,14 × 10 cm × 10 cm × 15 cm³
= 314 × 5 cm³
= 1570 cm²
V gabungan = V l + V ll
= 2093,33 cm³ + 1570 cm³
= 3663,33 cm³
