Question

im stuck.someone help?
A cone has a base radius of 2 millimeters and a height of 24 millimeters.

What is the volume of the cone?

A.
32π mm3

B.
384π mm3

C.
96π mm3

D.
16π mm3

Answer 1

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

Answer 2

v=1/3BH @mathmale

Answer 3

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

Answer 4

sorry

Answer 5

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

Answer 6

\[V=\frac{ 1 }{ 3} b h\]

Answer 7

a=pie(r^2)

Answer 8

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).

Answer 9

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

Answer 10

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

Answer 11

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

Answer 12

ok..

Answer 13

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

Answer 14

ohhhhhh ok, thanks!:)
