Question

The circumference of the hub cap of a tire is centimeters. Find the area of this hub cap. Use 3.14 for π. Use pencil and paper. If the circumference of the hub cap were​ smaller, explain how this would change the area of the hub cap.

Answer 1

Answer:

Area of the hub = 470.42 cm² (Approx.)

Step-by-step explanation:

Missing information;

Circumference of the hub = 76.87 cm

Value of π = 3.14

Find:

Area of the hub

Computation:

Circumference of the hub = Circumference of circle

2πr = 76.87

2(3.14)r = 76.87

6.28r = 76.87

Radius of hub = 12.24 cm

Area of the hub = Area of circle

Area of the hub = πr²

Area of the hub = (3.14)(12.24)²

Area of the hub = (3.14)(149.8176)

Area of the hub = 470.42 cm² (Approx.)

Yes,  If the circumference of the hub cap were​ smaller, Area will be small too.
