The circumference of the hub cap of a tire is 83.96 centimeters.

1. Find the area of this hub cap. Use 3.14 for [tex]\pi[/tex].

2. If the circumference of the hub cap were smaller, explain how this would change the area of the hub cap.

Answer :

Answer:

Area = [tex]561.2485[/tex] square centimeter

If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.

Step-by-step explanation:

As we know the circumference of a circle is [tex]2\pi r[/tex]

The radius of the hub cap needs to be devised to determine the area

[tex]83.96[/tex] [tex]= 2* 3.14*r[/tex]

[tex]r = \frac{83.96}{2*3.14}[/tex]

[tex]r = 13.37[/tex] centimeters

Area of the hub cap = [tex]\pi r^{2}[/tex]

Substituting the devised value of r in the above equation, we get -

[tex]3.14 * 13.37^2\\[/tex]

[tex]561.2485[/tex] square centimeter

If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.
