Answer:
Step-by-step explanation:
*The key word 'less than' means to subtract.

3(x) = 14 is incorrect. Multiplying is irrelevant to this problem, it's not saying Kiran's backpack is 3 times a number equal to Clare's backpack weight.
x = 143 is incorrect. This equation is unrealistic.
x = 14 - 3 is correct. This equation is explaining that Kiran's backpack is 3 pounds less than Clare's backpack (14)

Curl is defined as:
Which can be rewritten as:
This is because C1 lies on the xy plane and thus it's unit vector will be .
By similar arguments the rest will follow too.
Now, area of each circle will be:
Therefore, Curl, as per our definition will be:
Thus, Curl=
Which is the required answer.
