WebCurved Surface Area of Cone = πrl where r is the radius of the base and l is its slant height. We already know that cones constitute the right-angled triangle. As per Pythagoras Theorem, length of the slant side, l 2 = r 2 + h 2 Therefore, Slant height l =√r2+ h2 Furthermore, if a circle whose area is πr 2 is used to close the base. WebSurface area of cone = Area of sector + area of circle = πrs + πr 2 = πr (r + s) Surface area of a cone when given the slant height Example: A cone has a circular base of radius 10 cm and a slant height of 30 cm. …
