Surface Area Of Cone || Curved Surface alArea of Cone πrl || Total Surface Area Of Cone πr(r+l) A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex. A cone with the radius of its base r, its height h, its slant height c, and its angle θ. Surface area πr^2 + πrl Surface area The lateral surface area of a right circular cone is LSA=πrl where r is the radius of the circle at the bottom of the cone and l is the slant height of the cone. The surface area of the bottom circle of a cone is the same as for any circle, πr2. Thus, the total surface area of a right circular cone can be expressed as each of the following: Radius and height πr^2+πrl or πr(r+l) proof of circle formulas... link:    • Circle | circle formulas derivation in hin...   ‪@mohitsir‬ #cone
