t = 10 cm
Ditanyakan ~> Luas permukaan
Jawab ~> Luas alas & tutup tabung = (6160 cm³ : 10 cm) × 2
= 616 cm² × 2
= 1232 cm²
Diameter lingkaran = 616 cm² : 22/7
= 616 cm² × 7/22
= √196 cm² × 2
= 14 cm × 2
= 28 cm
Keliling lingkaran (p selimut tabung) = π × d
= 22/7 × 28
= 88 cm
Luas selimut tabung = p x l
= 88 cm × 10 cm
= 880 cm²
Luas permukaan tabung = 1232 cm² + 880 cm²
= 2112 cm²
