1 is 4 and 4 and 4 is 11 and 5 is 15
2x = 10√3
=> x = 10√3 / 2
=> x = 5√3
hence missing side of triangle is 5√3

Step-by-step explanation:
We are given that the diameter of the sand-shaped cone is 14 inches, and the height is 15 inches.
The volume for a cone is given by:

Where r is the radius and h is the height.
Since the diameter is 14, the radius is 7.
And we are given that the height is 15.
Therefore, the volume will be:

Use a calculator:

The volume of the cone is approximately 769.7 cubic inches.
