The volume \( V \) of a cone is calculated using the formula:
\[ V = \frac{1}{3} \pi r^2 h \]
where \( r \) is the radius of the base, \( h \) is the height, and \( \pi \) is approximately 3.14.
Given:
- Radius \( r = 5 \) inches
- Height \( h = 15 \) inches
Plug these values into the formula:
\[ V = \frac{1}{3} \times 3.14 \times (5)^2 \times 15 \]
First, calculate \( (5)^2 \):
\[ (5)^2 = 25 \]
Next, multiply this by the height:
\[ 25 \times 15 = 375 \]
Now, multiply by \( 3.14 \):
\[ 3.14 \times 375 = 1177.5 \]
Finally, divide by 3:
\[ \frac{1177.5}{3} = 392.5 \]
So, the volume of water the flower vase can hold is:
\[ 392.5 \, \text{cubic inches} \]
Therefore, the correct answer is:
\[ \boxed{392.5 \, \text{cubic inches}} \]
A hanging flower vase is in the shape of a cone with a radius of 5 inches and a height of 15 inches. What volume of water can the flower vase hold?
