Answer:

I. 94.99 in²

II. $0.23

Step-by-step explanation:

Given the following data;

Diameter of wheel = 11 inches

[tex] \pi = 3.14[/tex]

Cost of wheel = $21.35

[tex] Radius, r = \frac {diameter}{2} [/tex]

[tex] Radius, r = \frac {11}{2} = 5.5 \; inches [/tex]

Part A

To find the area;

We know that a wheel is circular in nature. Thus, the area of a circle is given by the formula;

[tex] Area, A = \pi r^{2} [/tex]

Substituting into the equation, we have;

[tex] Area, A = 3.14 * 5.5^{2} [/tex]

[tex] Area, A = 3.14*30.25[/tex]

Area, A = 94.99 in²

Part B

To find cost per square inch;

[tex] Cost \; per \; square \; inch = \frac {Cost \; per \; wheel}{Area \; of \; wheel} [/tex]

[tex] Cost \; per \; square \; inch = \frac {21.35}{94.99} [/tex]

Cost per square inch = $0.23
