To calculate the volume of a cone, you can use the formula:

\[ V = \frac{1}{3} \pi r^2 h \]

Where:

  • \( r \) is the radius of the base of the cone,
  • \( h \) is the height of the cone.

Given:

  • Radius \( r = 5 \) inches
  • Height \( h = 10 \) inches

Now, plug the values into the formula:

\[ V = \frac{1}{3} \pi (5^2) (10) \] \[ V = \frac{1}{3} \pi (25) (10) \] \[ V = \frac{1}{3} \pi (250) \] \[ V = \frac{250\pi}{3} \]

Now, using the approximate value of \( \pi \approx 3.14 \):

\[ V \approx \frac{250 \times 3.14}{3} \] \[ V \approx \frac{785}{3} \] \[ V \approx 261.67 \text{ in}^3 \]

Rounding this to one decimal place gives approximately \( 261.7 \) in³.

Therefore, the volume of the cone is approximately 261.7 in³.
