To calculate the volume of a cylindrical glass, you can use the formula for the volume of a cylinder:

\[ V = \pi r^2 h \]

Where:

  • \( V \) is the volume,
  • \( r \) is the radius of the cylinder,
  • \( h \) is the height of the cylinder.

Given:

  • Height \( h = 10 \) cm
  • Width (diameter) = 8 cm, therefore the radius \( r = \frac{8}{2} = 4 \) cm.

Now plug the values into the formula:

\[ V = \pi (4)^2 (10) \] \[ V = \pi (16) (10) \] \[ V = 160\pi \]

To get a numerical value, we can use \( \pi \approx 3.14 \):

\[ V \approx 160 \times 3.14 \approx 502.4 \text{ cubic centimeters} \]

Thus, the volume of the glass is approximately 502.4 cubic centimeters.
