Step-by-step explanation:
6/8 can be simplified to 3/4, if that helps.
Answer:
50
Step-by-step explanation:
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. For example: 25•16=400, which is the perfect square of 20. You could plug in other you would come up with the perfect square every time.
