The answer to (a)(b)(c) is 2,656
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
or 
Let
x-------> the pressure in PSI
y------> the volume of the gas in cubic inches
In this problem we have the point 
so

Find the constant k

substitute the values of x and y


the equation is

therefore
<u>the answer is</u>

Answer:
V= 301.44
Step-by-step explanation:
the formula for a cone is 1/3 Bxh
B= area of base
h= height
To find x, substract 72 and 78 from 180 since all triangles are 180°
180 - 72 - 80 = 30
So x = 30
To find y, x and y equal 180 so subtract 30 from 180
180 - 30 = 150
y = 150
x = 30, y = 150
