Why do you need to FIND the slant height if you have the [lateral height and] slant height?
Slant height is 39.98 cm
Assuming it is a right cone, use Pythagoras - slant height = hypotenuse, other two sides = radius of base, and height.
By using trigonometry or Pythagoras' theorem
Uisng the lateral area and tha radius, you should be able to find the height of the cone. Using the height and radius as the legs of a right triangle, use the Pythagorean Theorem. The hypotenuse is the slant height.
Why do you need to FIND the slant height if you have the [lateral height and] slant height?
the slant height is always 2 units bigger then the height
(slant height)2= (height)2+(1/2 side)2
Knowing the slant height helps because it represents the height of the triangle that makes up each lateral face. So, the slant height helps you to find the surface area of each lateral face.

Assuming it is a right cone, use Pythagoras - slant height = hypotenuse, other two sides = radius of base, and height.
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.

What do you mean by the radius of 4? Radius is used in circles. Do you mean that the breadth is 4? If so you can use Pythagoras's Theorem to find the 'slant height' (provided that it is a right-angle triangle) (slant height)2=52+42
