A cone has a radius of 3cm and height of 5cm, find total surface area of the cone. What is the total surface area of a cone if its radius = 4cm and height = 3 cm. cone, curved surface area, total surface area | The total surface area of a cone = Base area + latera surface area. To begin with we need to find slant height of the cone, which is determined by using Pythagoras, since the cross section is a right triangle. (The lateral area is a fancy name for the area of the surface that connects the base to the peak; in other words, everything but the base.) Use π = 3. Therefore, the total surface area of the cone is 83.17cm2 Example 2: The total surface area of a cone is 375 square inches. Surface Area of a Cone (Definition, Formula, Derivation, and Examples) The surface area of a cone is the area occupied by the cone’s surface in the 3D space. = πr[r+l] = 3.14×12[21+12] = 3.14×12[33] TSA of cone = 1243.44m2.
