Answer:

  • About 28 cm³

Explanation:

The shape of a straw may be modeled by a cylinder; thus, use the formula for the volume of a cylinder with length (or height) 25cm and diameter 12mm.

Formula for the volume of a cylinder:

       [tex]V=\pi \times (radius)^2\times height[/tex]

For the given straw:

  • radius = diameter/2 = 12mm /2 = 6mm

  • Convert to cm: 6mm × 1cm/10mm = 0.6cm

  • height: 25cm

Substitute and compute:

         [tex]V=\pi \times (0.6cm)^2\times 25cm\approx28.27cm^2\approx28cm^3[/tex]
