The slant height of a cone is the distance between the curved edge to the vertex at the top of the cone. It is used to calculate surface area.
The height would be The square root of the square of the slant surface length minus the square of the radius of the cone at the base.
Assuming it is a right cone, use Pythagoras - slant height = hypotenuse, other two sides = radius of base, and height.
Slant height is 7.81 inches.
A cone is a solid composed of a circle and its interior (base), a given point not on the plane of the circle (vertex) and all the segments from the point to the circle. A right cone is a cone where...
