Answer: 97.7 in
Step-by-step explanation: The perimeter is another name for circumference. Since we know that the formula for circumference is 2(pi)r, but we only want half of that.
Note that 2r is another way of writing the diameter (d).
In this case, we can use the formula d(pi)/2 + d (we’re adding d because d(pi)/2 will only give us the perimeter of the arch.
38(pi)/2 = 59.66
59.66 + 38 = 97.66
Rounded, that would be 97.7 in
It will take her 45 minutes to run 5 miles,because 27/3=9 and 9•5=45
