To find the volume of a cylindrical water bottle, we can use the formula for the volume of a cylinder:
\[ V = \pi r^2 h \]
Where:
- \( V \) is the volume,
- \( r \) is the radius,
- \( h \) is the height,
- \( \pi \) is approximately 3.14.
Given:
- Radius \( r = 2 \) inches,
- Height \( h = 10 \) inches.
Substituting the values into the formula:
\[ V = 3.14 \times (2)^2 \times 10 \] \[ V = 3.14 \times 4 \times 10 \] \[ V = 3.14 \times 40 \] \[ V = 125.6 \text{ in}^3 \]
Therefore, the volume of Gabriella’s water bottle is 125.6 in³.
