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.

What is the center of mass of a cone?
Center of mass of hollow cone is H/3 distance above its base and that of solid cone is 3H/10 distance above its base.
The surface area formula for a right cone is the same as the surface area formula for an oblique cone?
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.
A right circular cone has radius 5cm and height 8cm Find the lateral surface area of cone?
This cone has a lateral surface area of approximately 226.73cm2
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 lateral area of a cone with radius 12 and height of 9?
For a right circular cone, the lateral area is 565.49 units2
