The length of the arc intercepted by a central angle is the ratio of the angle to 360 degrees times the circumference. From the given values above,
S = (30° / 360°) x 2 x π x (6 ft)
S = π
The angle intercepted an arc which measures π feet. The answer is letter A.
3y^2 and -3/4y^2
5x and 2/3x
12x^2
Step-by-step explanation:

Answer:
The correct unit price would be $1.23.
The contractor divided 103.32 by 7, resulting in an error.
Step-by-step explanation:
If we know a dozen equals 12, then 7 dozen looks like:

Let's find our unit price:
<em>unit price =</em> 
Substitute.
<em>unit price = </em>
Divide.
<em>unit price = </em>
<em />
<em>__</em>
To find the error of the contractor, let's try substituting in a number (7) provided in the question to see if we get $14.76 per pair:

Divide.
