A round brass bar is 5m long and 14mm in radius, calculate its volume in cm^3

Answer»

Answer:

Volume of brass bar = 3080 cm³

length = 5M = 500 CM

radius = 14 MM = 1.4 cm

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