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
Yes, it can be a parallelogram. This is because both sides are parallel.
If we take the sequence terms apart and write the odd-numbered terms (the first, third, fifth, etc) and the even-numbered terms (the second, fourth, sixth, etc) in<span> own sequences we will get:
5 10 15
15 13 11
So, in the first sequence every term is obtained by adding five to the previous, and in the second sequence every term is obtained by subtracting 2 from the previous term. According to this logic, the next number in the series </span><span>5, 15, 10, 13, 15, 11, 20.</span>
