  • Find cone base area using a circle's formula, which is pi times (radius squared). Find cone slanted area with this formula:half of the length of the side, times the circumference of the base.. Add the results to get the total surface area.

  • Measure the cone's circumference with this formula: C = pi * d. C is circumference and d is its diameter. Measure the diameter, which is a line from the base's one side, through its center, to the opposite side.

  • Calculate cone slant height from its top to its base's side. Use your slant height and circumference measurement to calculate cone slanted area. Use step one's formula, where "s" is the slant height, and C is the circumference.

    Add your results for cone base area and cone slanted area to get the total cone surface area.

Can a cone and a cylinder have the same surface area?

Of course they can. The cone would have to be taller or have a wider base than the cylinder, but they could very easily have the same surface area. A cone and a fish can have the same surface area.


What is the formula for the surface area of a cone?

Area = πSr + πr² Where: S = the slant length of the cone r = radius of the base πr² = area of the base of the cone πSr = area of outside of cone -------------------------------------------------------------- The surface area of the cone is the sum of the area of the base and the slanted surface. The area of the base is the area of a circle = πr² The area of the slanted surface can be calculated by realising that if the slanted surface is cut by a straight line from the apex to the base it can be "unrolled" into a sector of a circle. Thus it is a fraction of the area of a circle. The length of the circumference of the sector is the length of the circumference of the base of the cone; the length of the whole circle from which this is a sector is the circle with radius of the slant height of the cone; thus: area slanted surface = πS² × ((2πr)/(2πS)) = πSr Thus the surface area of a cone = area base + area slant surface → surface_area_cone = πr² + πSr = πr(r + S) where r is the radius of the base and S is the slant height.

Where is the face of a cone?

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.
