A right cone has a slant height of 17 feet, and the diameter of the base is 16 feet. What is the height, h, of the cone?

Respuesta :

The height of the cone is 18.79 ft.

Step-by-step explanation:

Given,

The slant height (l) of the cone = 17 ft

The diameter = 16 ft

So, the radius (r) = 8 ft

To find the height (h) of the cone.

Formula

By Pythagoras theorem,

Perpendicular²+ base² = height²

Now,

Height² = 17²+8²

= 289+64

= 353

h = [tex]\sqrt{353}[/tex] - 18.7888 = 18.79 (approx)

Hence,

The height of the cone is 18.79 ft.
