Dik: d = 14 cm => r = d : 2 = 14 cm : 2 = 7 cm

t = 10 cm

Dit: V...?

Jawaban:

[tex]v =\pi \times r \times r \times t \\ \\ = \frac{22}{7} \times 7 \times 7 \times 10 \\ \\ = \frac{22 \times 7 \times 7 \times 10}{7} \\ \\ = \frac{10.780}{7} \\ \\ = { \bold{ \red{ \sf \: 1.540 \: {cm}^{3}}}} \\ \\ [/tex]

Kesimpulan

Jadi, volume tabung I adalah 1.540 cm³ {option d}.

Dik:d=14÷2=7

:r=7

:t=10

Penjelasan dengan langkah-langkah:

volume tabung=phi x r² x t

=22/7x7x7x10

22x7x10=1.540

7dengan7 adalah kelipatan
