Let x be the original radius. Given that a semicircle will have an arc length of half of a circumference and C=2pr, the arc length will be just pr.
Now the difference of arc is then going to be:
p(6+x)-px
p(6+x-x)
6p inches
So the arc will be 6p inches longer. Or if you wish to approximate...
≈18.85 inches
$315, i cant give a thorough explanation since i did it all in my head but basically amal gets 5 portions of the money and Salma gets 9, meaning she gets 4 more, so if 4 portions is $252 then it cant be any of the others since they are too low or way too high, $315 is the only reasonable one.

No, C is correct. 13 and 2 are prime numbers, 6 is not
Simplifying8f + -6f = 0
Combine like terms: 8f + -6f = 2f2f = 0
Solving2f = 0
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by '2'.f = 0
Simplifyingf = 0
