Hello!
The standard equation of a circle is x² + y² = r², when the center is at the origin.
So therefore, we just need to substitute the radius into the equation to find the appropriate equation.
x² + y² = (3)²
x² + y² = 9
Therefore, the equation of the circle is C, x² + y² = 9.
Part A
There are 2 cups in a pint, so 2 x 3 = 6
Plus 5 cups,
1 quart is equal to 1/4 of a gallon, and there are 4 cups in a gallon,
and another quart is 4 more cups,
so add all of the cups together:
6 + 5 + 4 + 4 = 19
Kelly is incorrect, because I added all of the cups together and I got 19.
Part B
Since 4 cups fit in a quart, and she has 4 quarts, her quarts only hold 16 cups, which isn't enough, because there are 19 cups.
Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)
The running time for an input size of 1000 will be 25 seconds.
To calculate the runtime of the Algorithm we need to know what an Algorithm is and how its runtime works.
<h3>What is the runtime of an
Algorithm?</h3>
A finite sequence of rigorous instructions, used to solve a critical problem of a specific class or for computational purposes is called an Algorithm. The time taken to complete the said task is called the runtime of an Algorithm.
Let us now solve the question about linear running time of an algorithm.
Input size(
)=200
Time taken(
)=5 seconds
Final input size(
)=1000
Let the final time taken be T.
Now we know that: 
Substituting the values we get
seconds .
Therefore the linear running time for an input size of 1000 is 25 seconds.
