The circumference of the hub cap of a tire is 80.1 centimeters. Find the area of this hub cap using 3.14 for pi.

Additionally, if the circumference of the hub cap were smaller, explain how this would change the area of the hub cap.

Answer :

Answer: The area is 510.25 cm². If the circumference of the cap were smaller then the area would be smaller as well

Step-by-step explanation:

First, you must find the radius

80.1 ÷ 3.14 = 25.5

25.5 ÷ 2 = 12.75 <---- radius

Then from that, you find the area

A=πr²

12.75² = 162.5

162.5 × 3.24 = 510.25

Hope this was helpful!

Answer:

510.25 cm².

Step-by-step explanation:

First, your gonna need to find the radius before continuing

80.1 ÷ 3.14 = 25.5

25.5 ÷ 2 = 12.75

Find the area

A=πr²

12.75² = 162.5

162.5 × 3.24 = 510.25
