Question

The circumference of the hub cap of a tire is 80.89 centimeters. Find the area of this hub cap.

Answer 1

520.89 cm²

Step-by-step explanation:

IN GIVEN QUESTION

The hubcap of the tire's circumference is 80.89 centimetres.

We must determine the radius of this hub cap, which we can do by using the circumference method to determine its area

now :

2πr = 80.89 cm

r = 80.89/ 2× 3.14

r = 12. 88 cm ( approx)

Area of hub cap = πr²

Area = 3.14 ×12.88² = 520.89 cm²

Answer 2

1634.77

Explanation:

2πr= circumference

80.89=2πr

80.89/ πr= r

r= 12.87

area= πr^2

area= 12.87 π^2

area= 1634.77
