Are these correct:
3) Find the capacity in gallons of a drum that is coneshaped if the radius is 9 feet, and the slant height is 41 feet. (first find the volume)
Volume in cubic feet = 3477.74306 cubic feet
Capacity in gallons = 26013 gallons (Round answer to the nearest gallon) (Use 1 cu ft = 7.48 gallons)

use Pythagoras to find the perpendicular height, realize that 41 is the hypotenuse.
You used 41 as the height, that is your error.
(see if you can get 3394)
adjust your capacity accordingly
