To solve this problem, we need to clarify what dimensions are given and how they relate to a cone's geometry.
We have:
- The height from the bottom to the middle (which is likely the height of the cone) is 5 feet.
- The slant height (the outer angled line) of the cone is 13 feet.
In a right circular cone, the relationship between the radius (\( r \)), height (\( h \)), and slant height (\( l \)) can be expressed using the Pythagorean theorem:
\[ l^2 = r^2 + h^2 \]
Where:
- \( l \) is the slant height,
- \( r \) is the radius,
- \( h \) is the height.
Given:
- \( h = 5 \) feet,
- \( l = 13 \) feet.
We can substitute these values into the equation:
\[ 13^2 = r^2 + 5^2 \]
Calculating the squares:
\[ 169 = r^2 + 25 \]
Now, solve for \( r^2 \):
\[ r^2 = 169 - 25 \] \[ r^2 = 144 \]
Taking the square root to solve for \( r \):
\[ r = \sqrt{144} \] \[ r = 12 \]
Thus, the radius of the cone is 12 feet.
