### Cone Volume Problem

#### Question:
15. In the diagram below, a right circular cone has a diameter of 8 inches and a height of 12 inches. What is the volume of the cone to the nearest cubic inch?

#### Diagram Description:
- The diagram is a right circular cone.
- The cone has a diameter of 8 inches.
- The height of the cone is 12 inches.

#### Diagram:
- A right circular cone is shown with a base diameter of 8 inches.
- A perpendicular height from the base to the apex is 12 inches.

#### Question Options:
- A. 603
- B. 481
- C. 201
- D. 804

To solve the problem, use the formula for the volume of a cone:
\[ \text{Volume} = \frac{1}{3} \pi r^2 h \]

Where:
- \( \pi \) (pi) is approximately 3.14159.
- \( r \) is the radius of the base.
- \( h \) is the height of the cone.

Given data:
- Diameter = 8 inches, so Radius \( r = \frac{8}{2} = 4 \) inches.
- Height \( h = 12 \) inches.

Now, substitute the values into the volume formula:
\[ \text{Volume} = \frac{1}{3} \pi (4)^2 (12) \]
\[ \text{Volume} = \frac{1}{3} \pi (16) (12) \]
\[ \text{Volume} = \frac{1}{3} \pi (192) \]
\[ \text{Volume} \approx \frac{1}{3} (3.14159) (192) \]
\[ \text{Volume} \approx 201.062 \]

Hence, the volume of the cone is approximately 201 cubic inches.

### Correct Option:
- C. 201
