Suppose you have a cone with slant height='l' and base radius 'r' and perpendicular height 'h' Curved surface area of COne=pi*r*l =pi*r*(squareroot(r2+h2))

find the surface area of the cone and add it to the surface area of the base so the formula would be pi radius s plus pi radius squared
Calculate them and compare.
i have an answer for both a frustum of a pyramid and a frustum of a cone which do you need frustum of a cone just give both of them
pi * r * s, where r is the radius of the base and s is the distance along the edge of the cone from the top to the base (not the height).
Unless the context suggests otherwise, the two are the same. However, you may, for example, be required to find the curved surface area of a cylinder and [then] the total surface area. In that case the total surface area would include the areas of the two end faces.
Use a calculator and you'll get yurh answer
The answer is squareroot r2+h2 squareroot radiusxradius + heightxheight
Curved Surface Area of a Cone:Multiply the base radius of the cone by pi. Multiply your answer by the length of the side of the cone.Then add the surface area of the base of the cone using the area of a circle = pi x r2
When you make a cone, you fold the cone along its slant height and thus you get the cone which is curved. So when you need to find the curved surface area (Which excludes the base) you need to use the same slant height that you folded the paper along which gave you the cone. Check out the links attached. It has some illustrations which will help.
V = 1,232 cm3
Curved surface area = pi*radius*slant length Voume in cubic cm = 1/3*pi*radius2*height
The surface area of a polyhedron can be calculated by first calculating the area of each of its polygonal surfaces and adding these together.The surface area of some curved solids (sphere, cylinder, cone) can be calculated from formula but for most curved solids are more complicated and require integration.
The volume of a cone can be calculated using the formula V = (1/3)πr^2h, where r is the radius and h is the height. To find the radius, use the formula A = πrℓ, where A is the curved surface area and ℓ is the slant height. Given A = 550 cm and h = 25 cm, you can find the radius and then calculate the volume of the cone.
The surface area of a right cone is the amount of square units that is needed to cover the surface of a cone. To find a surface area of a right cone , follow this formula S.A = 3.14rl + 3.14r(r) I hope it helped you.
2(pi)(r)(h)=the area of the curved surface
This cone has a lateral surface area of approximately 226.73cm2
Surface area of a sphere = 4*pi*radius2
