Answer:


h=8.48\ \text{inches}

Explanation:

Given that,

Radius of cone, r = 7 inches

Slant height of the cone, l = 11 inches

We need to find the height of the cone. Let the height be h. Using trigonometry to find it as follows :


h^2+r^2=l^2\\\\h=√(l^2-r^2)\\\\h=√(11^2-7^2)\\\\h=8.48\ \text{inches}

So, the height of the cone is equal to
8.48\ \text{inches}.
