Answer:

The area of this hub cap is about 470.46 square centimeters.

Step-by-step explanation:

Circumference (C) = 2π radius

Replacing with the values given:

76.87 = 2 (3.14) r

Solving for r (radius)

76.87/ (2x 3.14) =r

r = 12.24 cm

To find the Area:

Area of a circle = π r^2

A = 3.14 (12.24)^2

A = 470.46 cm2

If the circumference of the hub is smaller, the area is also smaller because it means that the radius of the circle decreases.
