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:
you are adding a dollar and 50 cents each time
Step-by-step explanation:
then find your y and x and plot it
Answer:
{ x | 1, 2, 3, 4, 5, 6, 7, 8, 9 }
Step-by-step explanation:
We note that points between integer values have been excluded, so domain consists of integer x-values from 1 to 9, or
{ x | 1, 2, 3, 4, 5, 6, 7, 8, 9 }
and <em>not</em>
1 <= x <= 9
I would say 13 3/4 but dont take me for my word
