Calculate the volume of the cone:
1. V_{\text{cone}} = \frac{1}{3} \pi (7)^2 (28)
2. V_{\text{cone}} = \frac{1}{3} \pi \cdot 49 \cdot 28
3. V_{\text{cone}}=1436.76cm^3
Calculate the volume of the pyramid:
1. V_{\text{pyramid}} = \frac{1}{3} \times 154 \times 28
2. V_{\text{pyramid}} = \frac{1}{3} \times 4312
3. V_{\text{pyramid}} = 1437.33 \, \text{cm}^3
Compare the two volumes:
- V_{\text{cone}}\approx1436.76\,\text{cm}^3
- V_{\text{pyramid}} = 1437.33 \, \text{cm}^3
The pyramid has a greater volume of approximately 1437.33\,\text{cm}^3 compared to the cone's volume of 1436.76\,\text{cm}^3 .
