Materi : Bangun Ruang Sisi Lengkung
Lp = 2 × π × r² + π × d × t
Lp = 2 × 3,14 × 6 × 6 + 22/7 × 24 × 35
Lp = 6,28 × 36 cm² + 22 × 24 × 5
Lp = 226,08 cm² + 110 cm × 24 cm
Lp = 226,08 cm² + 2.640 cm²
{ Lp = 2.866,08 cm² }
Keterangan :
π = 3,14 ⇒ Luas alas dan tutup tabung
π = 22/7 ⇒ Luas selimut tabung
Semoga bisa membantu
