Find the area of the wheel:
Area of a circle is found using the formula:
Area = PI x r^2
9 inch would be the diameter, so the radius would be 9/2 = 4.5 inches.
The area would be 3.14 x 4.5^2 = 63.6 square inches.
Now divide the price by the area to get price per square inch:
Cost per square inch = 18.60 / 63.6 = $0.29 (rounded to the nearest cent)
Answer:
Step-by-step explanation:
================================================
The "<em>constant rate of change</em>" is also known as the slope (in straight line equations).
The equation is in <em>slope-intercept form</em>.
================================================
<em>Slope-Intercept Form is: </em>
<em></em>
================================================
<em>Since '5' takes up 'm's spot, it is the slope, or the constant rate of change. </em>

Answer:
48/37
Step-by-step explanation:
Use the formula (y1 - y2)/(x1 - x2).
Plug in your x and y values to get (92 + 4)/(81 - 7).
Simplify down to get 96/74 and simplify again to get 48/37.
