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.

True. This is because the slant height of an oblique cone cannot be defined.

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

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

This cone has a lateral surface area of approximately 226.73cm2

The first step in finding the surface area of a cone is to measure the radius of the circle part of the cone. The next step is to find the area of the circle, or base. The area of a circle is 3.14 times the radius squared (Ï€r2). Now, you will need to find the area of the cone itself. In order to do this, you must measure the side (slant height) of the cone. Make sure you use the same form of measurement as the radius.You can now use the measurement of the side to find the area of the cone. The formula for the area of a cone is 3.14 times the radius times the side (Ï€rl).So the surface area of the cone equals the area of the circle plus the area of the cone and the final formula is given by:SA = Ï€r2 + Ï€rl

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

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 Ï€ 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, Ï€ r2Thus the total surface area of a right circular cone is: Ï€ r l + Ï€r2 OR Ï€ r (l + r)

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.

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))

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 formula will depend on what it is that you are trying to find: the volume or the surface area.
