Answer:
Therefore it is possible to find the circumference and area of a circle if we are given the radius or diameter of the circle.
Step-by-step explanation:
i) to find the area of a circle or circumference the radius , r, is required.
ii) if we are given the diameter, d. then we have to find the radius, r, by dividing the diameter by 2, that is 
.
iii) area of the circle is given by A = 
iv) circumference of the circle is given by C = 
Therefore it is possible to find the circumference and area of a circle if we are given the radius or diameter of the circle.

Answer: There are 14 long pieces she can cut.
Step-by-step explanation:
Since we have given that
Length of yards of ribbon is given by
Length of yards of ribbon pieces need to be cut is given by
Number of yards is given by
Hence, there are 14 long pieces she can cut.
For proportionality constant problems, set up the equation as,
,
Where x and y are the two variables you are comparing and <em>K </em>is the proportionality constant. If we take <em>Caramel Corn </em>values as x and <em>Cheddar Corn </em>values as y, and then solve for <em>K </em>for each ratio lines, we will get the same answer. Let's check.
,
, and
.
Hence, the proportionality constant, in this case <em>K,</em> is equal to 
or 1.5. First answer choice is correct.
ANSWER: 1.5
