Surface Area = Pi*radius(radius + slant height)
Archimedes
A cone has two surfaces, lateral surface and its circular surface at the base.The surface area of a cone is the sum of the areas of these two surfaces, i.e. (1) area of the lateral surface and (2) area of its base.Let us consider a right circular cone to find its surface area.The lateral surface area of a right circular cone is π r lwhere,r is the radius of the circle at the bottom of the cone, andl is the lateral height of the coneThe surface area of the bottom circle of a cone is the same as for any circle, π r2Thus the total surface area of a right circular cone is: π r l + πr2 OR π r (l + r)
T=L+B
For a right circular cone, by far the easiest way to find the surface areais to know the formula for the area, and apply it.The formula for the area of a right circular cone isArea = (pi x R) x (R + L)R = radius of the baseL = length of the slant from the base to the apex
Surface Area = Pi*radius(radius + slant height)

This cone has a lateral surface area of approximately 226.73cm2
surface area of right circular cylinder = 2 pi r h +2 pi r2
The sphere has a surface area-to-volume ratio of 0.15m^-1, which means it has a relatively low surface area compared to its volume. This indicates a more compact shape. On the other hand, the right circular cylinder with a ratio of 2.2m^-1 has a higher surface area compared to its volume, suggesting it is more elongated or spread out.

The surface area is 69.12ft2
The relationship between the surface areas of cylinders, cones, and spheres is that the surface area of a cylinder is equal to the sum of the areas of its two circular bases and its curved surface area, the surface area of a cone is equal to the sum of the area of its circular base and its curved surface area, and the surface area of a sphere is equal to four times the area of its circular base.
The lateral surface area of a right circular cone with a radius of 12cm and a slant height of 20cm is approximately 754cm2
