Explanation:
The perimeter of the track is the two circumferences of the semicircles (when combined, they form one circle, so we can just find the circumference of the circle) added to the lengths of the rectangle (
160
meters).
To find the circumference of the circle, we need to know the diameter.
Circumference of a circle:
d
π
or
2
r
π
, where
d
represents diameter and
r
represents radius
The diameter of the circle happens to be the same as the width of the rectangle. We know that the area of a rectangle is found by multiplying its length by its width. We know that the area is
14400
and that its length is
160
.
Width: area divided by length
14400
160
=
90
The diameter of the circle and the width of the rectangle is
90
meters.
Circumference:
90
⋅
π
=
90
π
→
If you are using an approximation such as 3.14 for
π
, multiply that by 90
Add
160
⋅
2
to the circumference since the lengths of the rectangle are also part of the perimeter.
160
⋅
2
=
320
90

320

Answer:
If you go to a website with a graph place the points and look where the line sets
Step-by-step explanation:
Jonah recorded the points his team scored during its last nine basketball
games. The mean number of points scored was 42 and the MAD Was 4.4.
The MAD shows that the scores generally varied greatly from the mean.
The scores were mostly less than
38 (42 -4.4 = 37.6)
greater than
46 (42 + 4.4 = 46.4).
