An ice cream cone making company sells their cones for $ .25 per square foot. Their cones have a slant height of 10 inches and a diameter of 6 inches. How much money (in dollars and cents) would they make for filling an order for 500 cones? (Use pi = 3.14)

From what you've written, I think you need:
For surface area of cone: A= pi*r*l
Where r= radius (half of diameter)
and l= slant height length (your 10 inches)
Work out total A, then divide by 0.25 to find cost per cone and multiply by 500 cones
Edit: yru1too, you're confusing the issue. It's the surface AREA of the cone, not the volume!
Arghh. so's Jennifer, don't you people read the question properly?

Cone area
A =
2ÏR
------ * ÏL^2 =
2ÏL
A = ÏRL = Ï(6 in)(10 in)(1 ft^2/ 144 in^2)
Money = $0.25(500)(Ï)(6 in)(10 in)(1 ft^2/ 144 in^2)

use the formula for the volume of a cone: 1/3Ïr2h
than multiply that by 500 and you have your answer good luck
Also, thank you for not asking someone to do it for you, but rather what forumla to use....
Have a GREAT day! (hope homework doesn't keep you so bogged down you can't enjoy your weekend)

http://www.mathwords.com/r/right_circular_cone.htm
volume=1/3 (pi r squared) x h
h being the heigt of the cone, which you need to figure out using the pythagorean theorem
