Curved surface area of a cone = pi*radius*slant length

It says so in the formula
Volume of cone = Pi/4 x D2 x H/3 where D = diameter H = vertical height
When a cone is sliced parallel to the base then the shape produced is a circle. If the cone is sliced at an angle so that the cut goes completely through the cone then an ellipse is produced. If the cut is made perpendicular to the cone's base then the shape produced is a parabola.
The intersection of a right circular cone and a plane that is parallel to the edge of the cone is a parabola. However, if the vertex of the cone lies on the plane, then the intersection is simply two intersecting lines.
You cant find the area of the throat because the throat is 3-D and the area is only for 2-D measurements
