Answer» r1 = 28 ÷2 = 14 cm r2 = 24 ÷ 2 = 12 cm Find the volume of the wood: Volume = πh(r1² - r2²) Volume = π(35)(14² - 12²) Volume = 5720 cm³ Find the mass of the pipe: 1 cm³ = 0.6g 5720 cm³ = 0.6 x 5720 = 3432g or 3.432 kg

Answer»

r1 = 28 ÷2 = 14 cm

r2 = 24 ÷ 2 = 12 cm

Find the volume of the wood:

Volume = πh(r1² - r2²)

Volume = π(35)(14² - 12²)

Volume = 5720 cm³

Find the mass of the pipe:

1 cm³ = 0.6g

5720 cm³ = 0.6 x 5720 = 3432g or 3.432 kg
