Question

hitunglah luas selimut tabung dan volume tabung jika
r=14
t=10​

Answer 1

Verified answer

[tex]ls = 2 \times \pi \times r \times t[/tex]

[tex]ls = 2 \times \frac{22}{7} \times 14 \times 10[/tex]

[tex]ls = 2 \times 22 \times 2 \times 10[/tex]

[tex]ls = 44 \times 20[/tex]

[tex]ls = \boxed{880 \: \: {cm}^{2} }[/tex]

[tex] \\ [/tex]

[tex]v = \pi \times r \times r \times t[/tex]

[tex]v = \frac{22}{7} \times 14 \times 14 \times 10[/tex]

[tex]v = 22 \times 2 \times 14 \times 10[/tex]

[tex]v = 44 \times 140[/tex]

[tex]v = \boxed{6160 \: \: {cm}^{3} }[/tex]

Answer 2

Penjelasan dengan langkah-langkah:

Luas selimut :

= 2·π·r·t

= 2·22/7·14·10

= 2·22·2·10

= 880 Cm²

Volume :

= π × r × r × t

= 22/7 × 14 × 14 × 10

= 22 × 2 × 14 × 10

= 6.160 Cm³
