Answer:
153.94
Step-by-step explanation:
A = pi * r^2
A = pi * 7^2 (radius is half of the diameter)
A = 49 * pi
A = 153.94

Answer:
The constant of proportionality is for every 1 x, there is 0.25 y. y = 0.25, and on a graph, x is always the "1." Since x is worth 1, y must be worth 0.25.

Equation of the graph is y = –9x + 360.
Solution:
Take any two points on the line.
Let the points are (40, 0) and (0, 360).
Slope of the line:
m = –9
The slope is –9.
y-intercept is the point where the line intersects with the y-axis.
y-intercept = 360
b = 360
Slope-intercept form:
y = mx + b
y = –9x + 360
Equation of the graph is y = –9x + 360.
The volume will be 16*10*12=1920 cubic inches. This is enough for 1920 cubic inch boxes.
