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
