To order the cones from greatest volume to least volume, we need to consider the volume formula for a cone, which is given by:
\[ V = \frac{1}{3} \pi r^2 h \]
where \( r \) is the radius and \( h \) is the height. We'll assess each option by calculating the values of \( r^2 \) and highlighting the corresponding heights:
-
E: Radius = 8 cm, Height = 15 cm
\[ r^2 = 8^2 = 64, \quad h = 15 \] Volume factor = \( 64 \times 15 = 960 \) -
B: Radius = 4 cm, Height = 15 cm
\[ r^2 = 4^2 = 16, \quad h = 15 \] Volume factor = \( 16 \times 15 = 240 \) -
D: Radius = 6 cm (diameter 12 cm), Height = 9 cm
\[ r^2 = 6^2 = 36, \quad h = 9 \] Volume factor = \( 36 \times 9 = 324 \) -
C: Radius = 3 cm, Height = 8 cm
\[ r^2 = 3^2 = 9, \quad h = 8 \] Volume factor = \( 9 \times 8 = 72 \) -
A: Radius = 5 meters, Height is unknown (but slant height is 13 meters)
We can't determine volume precisely without the height. However, slant height must be √(r² + h²), which suggests it wouldn't exceed E due to constraints on r and typical dimensions.
Placing the cones in order of volume from greatest to least based on the calculations and evidence:
- E: (Volume Factor = 960)
- B: (Volume Factor = 240)
- D: (Volume Factor = 324)
- C: (Volume Factor = 72)
- A: (Volume not definitively calculable, but likely less than C)
Final order:
- E
- B
- D
- C
- A
