Answer: 
Step-by-step explanation:
The equation of a circle in the general form is:

The equaton of a circle in standard form is:

Where the center is at <em>(h, k)</em> and <em>r</em> is the radius
To write the equation of a circle from general form to standard form, you must complete the squaare, as you can see below:
1- Given the equation in general form:

2- Complete the square:
-Group the like terms and move the constant to the other side.
- Complete the square on the left side of the equation.
- Add the same value to the other side.
Then you obtain:

Answer:

Explanation:
The<em> cone</em> is said to <em>fit perfectly inside the can</em> when the diameter of the cone and its height are equal to those of the can.
The shape of a can can be considered a cylinder.
The<em> volume of a cone that fits into the can</em> is 1/3 the volume of the can.
Thus, the volume of our cone is (1/3) × 42 unit³ = 14 units³
