Final answer:
The diameter of the cone is 8 inches.
Step-by-step explanation:
To find the diameter of the cone, we can use the formula for the diameter of a cone, which is twice the radius. Given that the radius is 4 inches, we multiply it by 2 to get the diameter. Therefore, the diameter is 8 inches.
In mathematical terms:
![\[ \text{Diameter} = 2 * \text{Radius} \]](https://img.qammunity.org/2024/formulas/physics/high-school/qd5exrmbqertaemywjv4bk7ibf4g85jne3.png)
![\[ \text{Diameter} = 2 * 4 \, \text{inches} = 8 \, \text{inches} \]](https://img.qammunity.org/2024/formulas/physics/high-school/ucegblz088v9906isj9o70g5rh493qrqw0.png)
So, the cone with a height of 13 inches and a radius of 4 inches has a diameter of 8 inches.
This calculation is based on the geometric properties of a cone, where the diameter is twice the radius. It's a straightforward calculation that doesn't involve complex steps. Understanding the relationship between the diameter and radius of a cone is crucial for solving such problems.
