Answer:

456.73 cm²

Step-by-step explanation:

Area of a circle = πr²

The radius of the hub cap

= 75.74÷3.14÷2

= 12.06 cm (rounded to the nearest hundredth)

The area of the hub cap

= 3.14 × 12.06²

= 456.7314968152...

= 456.73 cm² (rounded to the nearest hundredth)

Circumference means the perimeter of a circle. So if the perimeter of a shape is smaller, it makes the shape turn out to be smaller.

So the area of the hub cap will be smaller.
