Answer:

423,900 cm³

Step-by-step explanation:

diameter = 60 cm

radius = ⁶⁰/₂ cm = 30 cm

length = 3 m = 3 × 100 cm = 300 cm

┈

[tex]\frac{1}{2} \times 3.14 \times 30^2 \times 300[/tex]

[tex] = 3.14 \times 900 \times 150[/tex]

[tex] = 3.14 \times 135,000[/tex]

[tex] = \bold{423,900 \: cm^3}[/tex]
