## anonymous one year ago An ice cream store is making waffle cones. The finished cone should have a radius of 1 inch and be 5 inches tall. The slant height of the cone is 5.1 inches. How much waffle will they need to make each cone? Express your answer to the nearest square inch.

So you will need the cone formula. $SA = \pi r(r+\sqrt{h^2+r^2})$ r is the radius. h is the height.

for these questions it is quite simple. You simply plug numbers into the formulas.

I got 19.15

so would my answer be 19?

5. anonymous

yes and that would round to 19. I think you used 3.14 or something, because i got 19.16
