[Done] Cone W has a radius of 6 cm and a height of 5 cm. Square pyramid X has the same base area and height as cone W. Paul and Manuel disagree on the reason why the volumes of cone W and square pyramid X are related. | Paul | Manuel | |---|---| | The volume of square pyramid X is equal to the volume of cone W. This can be proven by finding the base area and volume of cone [tex]$W$[/tex], along with the volume of square pyramid X. | The volume of square pyramid X is equal to the volume of cone W. This can be proven by finding the base area and volume of cone [tex]$W$[/tex], along with the volume of square pyramid X. | | The base area of cone [tex]$W$[/tex] is [tex]$n(d)=n(12)=37.68 cm^2$[/tex]. | The base area of cone [tex]$W$[/tex] is [tex]$\pi(r^2)=\pi(6^2)=113.04 cm^2$[/tex]. | | The volume of cone W is [tex]$\frac{1}{3}[/tex] (area of base)( h )=[tex]$\frac{1}{3}(37.68)(5)=62.8$[/tex] [tex]$cm ^3$[/tex]. | The volume of cone [tex]$W$[/tex] is [tex]$\frac{1}{3}[/tex] (area of base)(h) =[tex]$\frac{1}{3}(113.04)(5)=[/tex] [tex]$188.4 cm^3$[/tex]. | | The volume of square pyramid X is [tex]$\frac{1}{3}[/tex] (area of base)(h) =[tex]$\frac{1}{3}(37.68)$[/tex] (5) [tex]$=62.8 cm^3$[/tex]. | The volume of square pyramid [tex]$X$[/tex] is [tex]$\frac{1}{3}[/tex] (area of base)(h) =[tex]$\frac{1}{3}$[/tex] [tex]$(113.04)(5)=188.4 cm^3$[/tex]. | Examine their arguments.
