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 l
where,
r is the radius of the circle at the bottom of the cone, and
l is the lateral height of the cone
The surface area of the bottom circle of a cone is the same as for any circle, π r2
Thus the total surface area of a right circular cone is: π r l + πr2 OR π r (l + r)
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.
No, you cannot directly use the surface area formula for a right cone to find the surface area of an oblique cone. Although both types of cones have a circular base and a slant height, the oblique cone's geometry differs, affecting the calculations for lateral surface area and overall surface area. To find the surface area of an oblique cone, you'll need to account for its specific dimensions and geometry.

Yes, it is true that the surface area formula for a right cone cannot be directly applied to an oblique cone. While both have a circular base and a slant height, the lack of a perpendicular height in an oblique cone affects the calculations for lateral surface area and total surface area. To find the surface area of an oblique cone, you must account for its specific geometry, typically involving more complex calculations.
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

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
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.

Calculate them and compare.
Yes, you can use the surface area formula for a right cone to find the surface area of an oblique cone, as the surface area calculation primarily depends on the slant height and the radius of the base, which are applicable to both types of cones. The surface area ( S ) of a cone is given by ( S = \pi r (r + l) ), where ( r ) is the radius of the base and ( l ) is the slant height. The key difference lies in determining the slant height for an oblique cone, which may require additional geometric considerations. Once the appropriate dimensions are established, the formula remains valid.
The formula to find the lateral area ( A ) of a right cone is given by ( A = \pi r s ), where ( r ) is the radius of the base of the cone and ( s ) is the slant height. This formula calculates the surface area of the cone's curved surface, excluding the base.
