Answer:

343[tex]\pi[/tex]

Step-by-step explanation:

Volume of a cone is [tex]\frac{1}{3}[/tex][tex]\pi[/tex][tex]r^{2}[/tex]*h

If the diameter=14 and r= [tex]\frac{diameter}{2}[/tex] then r= 7

[tex]7^{2}[/tex]= 49

49*21=1029

[tex]\frac{1029}{3} = 343[/tex]

if it asks to round multiply 343 by pi and round
