Please type in the formula for the volume of a cone.  If unsure, look up this formula (Google "volume of cone."

v=1/3BH @mathmale

mathmale · Answer

that'd be fine if you'd please enclose that "1/3" inside parentheses.

anonymous · Answer

sorry

What is the formula for the area of a circle (which is what the base is)?

mathmale · Answer

$$V=\frac{ 1 }{ 3} b h$$

anonymous · Answer

a=pie(r^2)

mathmale · Answer

becomes$$V=\frac{ 1 }{ 3  } \pi r^2  h$$

both r and h are given, and are in mm.  Substitute the given values into this formula (immediately above).

mathmale · Answer

Yes, the area of the base is $$A _{base}=\pi r^2$$

anonymous · Answer

And also think about what each variable in your volume formula stands for... B = Area of Base, H = length of Height.

mathmale · Answer

... and you can see that in my volume formula (above).

anonymous · Answer

ok..

mathmale · Answer

$$A _{cone}=\frac{ 1 }{ 3 } \pi (?)^2 (?)$$

anonymous · Answer

ohhhhhh ok, thanks!:)
