Answer: Im pretty sure it would be 67, find area of each side then add
Answer:
28.27
circumference of finding a circle divided by two.

(2×3.14×9)/2
56.55/2
28.27
First find the slope of the line connecting these two points:
6-5
m = ------------ = -1/2
-4+2
Substitute this slope into y = mx + b: y = (-1/2)x + b.
Next, subst. 5 for y and -2 for x, and find b:
5 = (-1/2)(-2) + b, or 5-1=b. Then b = 4, and
the equation of the line is y = (-1/2)x + 4.
904.78 is the amount of air it can hold.
