Jawab:
75,36 cm²
Penjelasan dengan langkah-langkah:
Lp Kerucut = r (r+s)
= 3,14 . 3 (3+5)
= 3,14 . 24
= 75,36 cm²
Semoga Membantu
Jawaban:
L = 75,36 cm²
Keterangan :
L = Luas permukaan kerucut (cm²)
π = 22/7 atau 3,14
r = Jari-jari kerucut (cm)
s = Garis pelukis (cm)
_______________________
L = π r (r + s)
= 3,14 × 3 cm (3 cm + 5 cm)
= 9,42 cm × 8 cm
= 75,36 cm² ✓
