The slant height of a cone is given by the formula , where r is the radius of the circle and h is the height from the center of the circle to the apex of the cone.
It is trivial to see why this formula holds true. If a right triangle is inscribed inside the cone, with one leg of the triangle being the line segment from the center of the circle to its radius, and the second leg of the triangle being from the apex of the cone to the center of the circle, then one leg will have length h, another leg will have length r, and by the Pythagorean Thereon, r2 + h2 = d2, and gives the length of the circle to the apex of the cone.

How do you find slant height?
the slant height is always 2 units bigger then the height
My formula for surface area of a cone uses l for slant height. Where does l come from I understand when people use s for slant height but why l?
I belive you can use any letter as a variable for slant height. yea... you can use any letter for any side or whatever that involves a variable (an unknown)
What is the slant height of cone of height 6 cm and base 30 cm?
Slant height is 16.16 cm
What is the slant height of the pyramid Louvre in Paris?
slant height of the pyramid Louvre in Paris=28 meters
How do you find the surface area of a pyramid?
Add the area of the base to the combined area of the faces Or just do this formula: PIxradius squared+ PIxradiusxThe slant height (if it is given)
