Explanation:
We can use the Pythagorean theorem to find the height of the cone, h. The slant height, s, and radius, r, of the cone form a right triangle where s is the hypotenuse. Therefore, we can write:
s^2 = r^2 + h^2
Substituting the given values, we get:
12^2 = 7^2 + h^2
Simplifying and solving for h, we get:
144 - 49 = h^2
95 = h^2
h = sqrt(95)
h ≈ 9.7
Therefore, the height of the cone is approximately 9.7 inches when rounded to the nearest tenth.
