:
A right triangle is formed: one leg is half the base length (3.5) going to the center.
the other leg is the height (center to vertex) and the slant height is the hypotenuse>
using a^2 + b^2 = c^2, where
a = 3.5
b = the height (h)
c = 15
3.5^2 + h^2 = 15^2
h^2 = 225 - 12.25
h =
h = 14.586 ft is the height
