A cone has a diameter of 18 units and height of 8 units. What is its volume?
sveta [45]
The radius of your cone is half of 18 units = 9 units.

The volume of any cone is      <span><span>V = (1/3) · (pi) · (radius)² · (height) </span>
</span>

-- Write '8' in place of 'height'.
-- Write '9' in place of 'radius'.
-- Write '3.142' in place of 'pi'.
-- Complete the arithmetic.
-- Bada-bing, you've got the volume.
