The surface area of a cone if the height is 21 and the diameter is 19 is 971.43 units2
A cone with height 24 and the base diameter 7 has a surface area of 305.17 units2
Total surface area of cone = (pi*radius*slant height) + (pi*radius2) Area = (pi*12*21) + (pi*122) = 1244.070691 or about 1244 square m
This cone has a lateral surface area of approximately 226.73cm2
Formula for surface area of a cone: π=pi (3.14159265) l=slant height, r=radius. πr2+πrl π62+π6*45=x 36π+270π=x 306π=x 961.33 cm2
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.4 Add your results for cone base area and cone slanted area to get the total cone surface area.
A cone with a diameter of 15 and a slant height of 15 will have a total surface area of about 530.14 units2
A cone with a diameter of 18km and a slant height of 20.1km has a total surface area of about 822.78km2
A cone with height 24 and the base diameter 7 has a surface area of 305.17 units2
204.2 units2
The lateral surface area is 549.78mm2
The curved surface area of the cone is 801.11 square units.

A cone with a radius of 2 and a height of 8.25 has a surface area of 65.9 units2
Total surface area of cone = (pi*radius*slant height) + (pi*radius2) Area = (pi*12*21) + (pi*122) = 1244.070691 or about 1244 square m
A circular cone has a height of 17mm and slant height of 21mm.find (1) the volume (2) the total surface area, of the cone the total surface area, of the cone Help me please Thank
Now that depends on if you mean outside surface area. A cone has an inside surface area too. Just adding my two cents. Not even good at math. But I can debate a point til the death!
Entire surface area of a cone = (pi*radius2)+(pi*radius*slant length) Use Pythagoras' theorem to find the slant length
