Step-by-step explanation:
4x + y = 8
-4x -4x
y = -4x+8
5x + 2y = 13
-5x -5x
2y/2 = -5x/2 + 13/2
y = -5/2x+13/2

Step-by-step explanation:
The volume of a cone can be calculated with the following formula:
Where "r" is the radius and "h" is the height.
The radius is half the diameter, then "r" is:
Since we know that radius and the height, we can substitute them into the formula.
The volume of the cone to the nearest cubic inch is:
