A right circular cone has a height of 3.75 in. The diameter of the base is 1.2 in. Find the volume of the cone.

Question

anonymous · Answer

use the cylender volume formula!

anonymous · Answer

1/3 H \[Pi] r^2

anonymous · Answer

Integrate[\[Pi] (r*h/H)^2, {h, 0, H}] --> 1/3 H \[Pi] r^2

ktklown - you can use the equation editor to make that more readable. :)

anonymous · Answer

yeah, that takes more effort :P

farmdawgnation · Answer

LOL. Nice.

$$\frac{1}{3}\pi r^2$$

Is that what you were going for? :P

anonymous · Answer

Yeah.... if they would render mathematica expressions i'd use it ;-)

farmdawgnation · Answer

Ah forgot the height

$$\frac{1}{3} H \pi r^2$$

Well, it's a really simple equation to solve. Just plug these values into that formula above:
$$H = 3.75$$
$$r = 0.6$$
Then just run the equation through a calculator and you're done. :)

Also worth noting the 0.6 for r is because the equation asks for the radius. Which is half of the diameter, which the problem tells you is 1.2.
