To calculate the volume of a cylinder, you can use the formula:
\[ V = \pi r^2 h \]
where \( r \) is the radius, \( h \) is the height, and \( \pi \) is approximately 3.14.
Given:
- Diameter of the cylinder = 10 inches, therefore the radius \( r = \frac{10}{2} = 5 \) inches.
- Height \( h = 8 \) inches.
Now plug the values into the formula:
\[ V = \pi (5)^2 (8) \] \[ V = \pi (25)(8) \] \[ V = 200\pi \]
Now, using \( \pi \approx 3.14 \):
\[ V \approx 200 \times 3.14 = 628 \]
Thus, the volume of the storage container is approximately \( 628.32 \) cubic inches.
The correct choice is:
C 628.32 in.³
