Circumference: 28π inches and Area: 196π in²
1) Considering that the diameter of each wheel is 28", then we can state that
D=2R ⇒ R = D/2 , R = 14
2) So to find out the circumference of the tire, we'll need to use the Circumference formula:
And now let's find out the area of the tire, by making use of another formula:
Plugging into that the radius length:
3) Hence, the answers are:
Circumference: 28π inches and Area: 196π in²
