Answer:
XY and XW
Step-by-step explanation:
Percent Error =

So, Ari's experimental value is ,

The accepted value is,

Here's The Work

Ari's Average Measurements Have An Percent Error Of 2.26%
We have been given that the diameter of a smaller circle is 7 km and the width of the circular path is 0.5 km. We are asked to find the area of the path.
The area of the path will be equal to area of larger circle minus area of smaller circle.
, where r represents radius of circle.
We know that radius is half the diameter, so radius of smaller circle would be
km.
The radius of the larger circle will be radius of smaller circle plus width of the path that is
km.





Therefore, the area of the circular path is approximately 11.8 square km.
It’s A because the formula for Rate is r=d/t
Answer:
Step-by-step explanation:
1. 11x = 44
x = 4
2. 3w = -9
w = -3
3. -4n = -16
n = 4
4. 6h = 36
h= 6
