The volume of a cone is equal to one third times the area of the base times the height: \[V=\frac{ 1 }{ 3 }Bh\]The base is a circle, whose area is equal to pi times the radius squared, so the volume is: \[V=\frac{ 1 }{ 3 }\pi r^2 h\]So you can plug in the radius and height here and solve for the volume

OpenStudy (anonymous):

What did you get when you plugged in?

OpenStudy (anonymous):

What happened to your pi? \[V=(1/3)\pi(1^2)(3)\]

OpenStudy (anonymous):

But when you simplify you get: \[V=\pi cm^3\]Because the 3 and (1/3) will reduce to 1

OpenStudy (anonymous):

No, the 3 will reduce with the 1/3. You'll just be left with pi

OpenStudy (anonymous):

Approximately, yes.

OpenStudy (anonymous):

What doesn't make sense about it?

OpenStudy (anonymous):

\[V=\frac{ 1 }{ 3 } \pi r^2 h=\frac{ 1 }{ 3 } \pi (1^2) (3)=\frac{ 3 }{ 3 }(1)\pi=(1)(1)\pi=\pi\]
