Help! Geometry problem needing solved!
The Creamy Creations makes waffle cones for its ice cream. For serving the cone is put in paper that must cover the surface. If the diameter of the top of the cone is 4 and a half inches and the height of the cone from the center to the tip is 7 and a third inches, what is the area of paper necessary to cover one cone??

cone lateral surface area=pi*a*sqrt(a^2+h^2)
where a=radius and h=height
a=4.5/2 h=7.33
area=54.198 sq inches
