it is 2(lw)+2(wh)+2(hl)
The face of the cone is on the bottom of the cone. For example, when looking at a birthday hat, the area that touches the table is the face of the cone. Same with an ice cream cone. The area of the ice cream cone that touches the ice cream is the face. Go to http://newsletters.hagerman.com/newsletters/Images/Ebul49/TIPS3.jpgthere you can see a picture of cone. The highlighted blue area is the face of the cone.
Just add the area of the six squares - that gives you 6a2, where a is the length of one side.
This is how you do it: Area = C(pi)r + (pi)r2 Where: C = the side length of the cone r = radius of the base (pi)r2 = the base of the cone C(pi)r = outside of cone
pi * r * (r + sqrt(r^2 + h^2))
Since the base of a cone is a circle, we substitute 2πr for p and πr2 for B where r is the radius of the base of the cylinder. So, the formula for the lateral surface area of a right cone is L. S. A. = πrl, where l is the slant height of the cone.
The suface are of a rectangular prism is the area of each face added together for a total.
The suface area of a sphere with a radius of 7 meters is 615.75m2
Surface area of a sphere = 4πr2
Their roots and their suface area
its in geelong so suck on that

the surface are of England is 50,346 suare miles

False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.
