Penjelasan dengan langkah-langkah:
volume tabung 1 ;
= πr²t
= 22/7 × 14 × 14 ×20
= 12320 cm³
Lp tabung 1 ;
= 2πr² + 2πrt
= (2 × 22/7 × 14 × 14) + (2 × 22/7 × 14 × 20)
= 1232 + 1760
= 2992 cm²
Volume tabung 2 ;
= πr²t
= 22/7 × 3,5 × 3,5 × 16
= 616 dm³
Lp tabung 2
= 2πr² + 2πrt
= (2 × 22/7 × 3,5 ×3,5) + (2 × 22/7 × 3,5 × 16)
= 77 + 352
= 429 dm²
