circumference rather than perimeter
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.
Cones, cylinders.
polygons have faces and cylinders and cone and spheres only has bases not faces.
The most general difference is: > The formula for the surface area of anything with a curved surface and edge will involve 'pi'. > The formula for the surface area of anything with only flat surfaces and straight edges won't.
