Answer 2

Answer:

Volume of brass bar = 3080 cm³

Step-by-step explanation:

length (h) = 5m = 500 cm

radius (r) = 14mm = 1.4 cm

$therefore. \: volume \: of \: brass \: bar \: = \\ = \pi {r}^{2}h \\ = \frac{22}{7} \times( {1.4})^{2} \times500 \\ = \frac{22}{7} \times 1.96 \times 500 \\ = 22 \times 0.28 \times 500 \\ = 3080 {cm}^{3}$
