Answer:
220 centimeters
Step-by-step explanation:
To find the circumference of a circle, use the formula [tex]C=2\pi r[/tex], where C is the circumference and r is the radius. Substitute our values in. Remember that the radius is half of the diameter, so it is 35.
[tex]C=2\pi r[/tex]
Plug in the radius of our tire.
[tex]C=2\pi (35)[/tex]
Simplify.
[tex]C=6.28(35)[/tex]
[tex]C=219.8[/tex]
The circumference is 219.80 cm. Round this up to 220 cm.
Good luck ^^
