The circumference of the hub cap of a tire is 80.07 centimeters. Find the area of this hub cap. Use 3.14 for \(\pi\).

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

The area of this hub cap is about how many square centimeters?

Answer :

The area of this hub cap is about 510.44625 cm².

What is Area of Circle?

The area of circle is pi times the square of the radius.

Area of circle =π r²

Circumference (C) = 2π r

80.07 = 2 (3.14) r

76.87/ (2x 3.14) =r

r = 12.75 cm

now, Area be

=π r²

= 3.14*12.5*12.75

=510.44625 cm²
