WebThe curved surface area of a cone is the area enclosed by the curved part of the cone. For a cone of radius 'r', height 'h', and slant height 'l', the curved surface area is as follows: Curved Surface Area = πrl square … WebCurved surface area of a cone. is 308 cm 2 its slant height is 14 cm. Find (i) radius of the base and (ii) total surface area of the cone. Medium Solution Verified by Toppr Given : Curved surface area of the cone =308cm 2 and Slant height or l=14 cm. Curved surface area of the cone =πrl 308= 722×r×14 r= (22×14)(308×7) r=7cm
Setting Up an Integral to Find A Cone
WebThis is a cross-section of the cone. The area of the strip of width d h that corresponds to h (from the apex) is 2 π r d h cos x Now r = h tan x Thus d A = 2 π h tan x cos x d h Thus the total area = ∫ 0 H 2 π h tan x cos x d h = π H 2 tan x cos x = π ( H tan x) ( H cos x) = π R S Hope that helps.
