<u><em>To cover a rectangular region of her yard, Penny needs at least 170.5 square feet of sod. The length of the region is 15.5 feet. What are the possible widths of the region?</em></u>
<u><em></em></u>
<u><em>L=length=15.5 ft; W=width; A=area=>170.5 sq ft</em></u>
<u><em></em></u>
<u><em>L*W=>170.5 sq ft Divide each side by L</em></u>
<u><em></em></u>
<u><em></em></u>
<u><em>W=>170.5 sq ft/L</em></u>
<u><em></em></u>
<u><em>W=>170.5 sq ft/15.5 ft=>11 feet</em></u>
<u><em></em></u>
ANSWER: To cover at least 170.5 sq ft. the width must be at least 11 feet.

To convert radians to degrees, multiply by 180/p, like this:
<span>degrees = radians x (180 / π ) </span>
<span>To convert degrees to radians, multiply by p/180, like this : </span>
<span>radians = degrees x ( π/180) </span>
<span>(A) This will use the formula for radians to degrees. </span>
<span>π/3 x (180/π) </span>
<span>The pi's cancel, leaving you with: 180/3 = 60 degrees
False
(B) </span><span>An angle that measures π/6 radians also measures 30°
</span>π/6 x (180/π) = 30 degrees.
<span>True
</span>(C) <span>An angle that measures π/3 radians also measures 60°
</span><span>π/3 x (180/π) = 60 degrees.
</span>True
(D) An angle that measures 180 degrees also measures <span>π/2</span>
π/2 x (180/π) = 90 degrees.
False
