  2. To find the curved surface area of a cone, we multiply the radius and slant height of the cone by pi(π), and the formula which is used to find the lateral surface area of a cone is, CSA of cone (LSA of cone) = πrl, where 'r' is the radius of the base and 'l' is the slant

  3. 2023年8月3日 · The surface area (total surface area) of a cone is the entire space occupied by the flat circular base of the cone and its curved surface. The surface area is expressed in square units such as m 2, cm 2, mm 2, and in 2. Here we will discuss how to find the surface area of a right circular cone.

  4. Rule: The curved surface area of a right circular cone equals the perimeter of the base times one-half slant height. The total surface area equals the curved surface area of the base. Example: The slant height of a conical tomb is 10.5 10.5 m.

  5. Curved Surface Area of a Cone. Radius (r) = Length (l) = = Curved Surface Area = πrl. Total Surface Area = πrl + πr2. Interactive formula to find the curved surface Area of a cone.

  6. Formula for Surface Area of a Cone. For a cone with a radius \hspace {0.2em} r \hspace {0.2em} r, height \hspace {0.2em} h \hspace {0.2em} h, and slant height \hspace {0.2em} l \hspace {0.2em} l, 1. Total surface area. 2. Lateral surface area or curved surface area. 3.

  7. Formula for Surface Area of Cone. (i) Curved Surface Area (CSA) curved surface area of cone = πrl π r l. where l is the slant height. (ii) Total Surface Area (TSA) Total surface area of cone = CSA + πr2 π r 2 = πrl π r l + πr2 π r 2. Note : l2 l 2 = r2 r 2 + h2 h 2. Here h is the height of the cone.
