Jawaban:

volume tabung :

d = 12 cm maka r = 12 : 2 = 6cm

t = 15 cm

π = 3,14

\begin{gathered}vol = \pi \times r {}^{2} \times t \\ = 3.14 \times 6 {}^{2} \times 15 \\ = 1.695,6cm {}^{3} \\ \end{gathered}

vol=π×r

vokume air dalam gelas :

\begin{gathered} \frac{4}{5} \times 1.695,6 = 1.356,48cm {}^{3} \\ \end{gathered}
