The circumference of a circle of diameter 13 m is 13π m, about 40.82 m.
(40.82 m)/(2.5 m) = 16.328
16 may be the best approximation of the number of pieces Malia will need. 17 pieces will make a barrier that is longer (larger diameter) than is needed.

Step-by-step explanation:
I used a calculator:3
If you have an average of 97.2 on your current exam and you get a 99 on your next exam, your average will increase.
- Mean in mathematics is the sum (total) of all the values in a set of data, such as numbers or measurements, divided by the total number of values.
- To find the average, sum all the values in the set. Then divide the total by the number of values.
We have the current examination mean, xold = 97.2
Now, we receive, x = 99 on the next examination, the new mean will be:
xnew = (xold + x)/N
xnew = (97.2+99)/2
xnew = 196.2/2
xnew = 98.1
The new average is 98.1
98.1 > 97.2
So if you score 99 on your next exam, your average will increase.
