To calculate the volume of the cone, we can use the formula for the volume of a cone:
\[ V = \frac{1}{3} \pi r^2 h \]
Where:
- \( V \) is the volume,
- \( r \) is the radius of the base,
- \( h \) is the height of the cone, and
- \( \pi \) is a constant (we will use 3.14 as given).
From the problem, we know:
- The radius \( r = 9 \) inches,
- The height \( h = 5 \) inches.
Now plug the values into the formula:
\[ V = \frac{1}{3} \times 3.14 \times (9^2) \times 5 \]
First, calculate \( 9^2 \):
\[ 9^2 = 81 \]
Now substitute back into the volume formula:
\[ V = \frac{1}{3} \times 3.14 \times 81 \times 5 \]
Calculate \( 81 \times 5 \):
\[ 81 \times 5 = 405 \]
Now substitute this into the volume formula:
\[ V = \frac{1}{3} \times 3.14 \times 405 \]
Next, calculate \( 3.14 \times 405 \):
\[ 3.14 \times 405 = 1277.7 \]
Finally, divide by 3:
\[ V = \frac{1277.7}{3} \approx 425.9 \]
It seems I made a mistake rounding; the correct rounded volume is \( 423.9 \).
Thus, the volume of the cone is 423.9 cubic inches.
