D
Penjelasan dengan langkah-langkah:
Luas tabung
= 2 . luas alas + keliling alas . tinggi tabung
= 2 . πa² + 2πa . h
= 2πa(a + h)
Jari Jari (r) = (a)
Tinggi (t) = ( h)
= 2 × Luas Alas + Luas Selimut
= 2 × πr² + 2πrt
= 2πr² + 2πrt
= 2πr ( r + t)
= 2πa ( a + h) < Opsi D >

Penjelasan dengan langkah-langkah:
Luas tabung
= 2 . luas alas + keliling alas . tinggi tabung
= 2 . πa² + 2πa . h
= 2πa(a + h)
Diketahui
Jari Jari (r) = (a)
Tinggi (t) = ( h)
Luas Tabung
= 2 × Luas Alas + Luas Selimut
= 2 × πr² + 2πrt
= 2πr² + 2πrt
= 2πr ( r + t)
= 2πa ( a + h) < Opsi D >
