If the axial section of a cone is an equilateral triangle and its area is 3, then the side area of the cone is 3______ .

If the axial section of a cone is an equilateral triangle and its area is 3, then the side area of the cone is 3______ .

The axis section of a cone is an equilateral triangle with an area of 3. For the axis section, there are 12.a2.32 = 3, A2 = 4 and a = 2, so the side area of the cone is π· 1.2 = 2 π. So the answer is 2 π
