Just took the test and got the the correct answer *\(♡°▽°♡)/*
Look at the image down below!!
Your answer would be 3.7m
hope this helped :)
The circumference (perimeter) of the tire is 2 x π x r (radius= half of the diameter):
So one complete rotation is equivalent to the perimeter that is 2 x 13 x 3.1459
= 81.68 inches & if he competed 10 rotation that means he run for 10 x 81.68 ===> 816.8 In
The perimeter would be 3/8+3/8+4/5+4/5= 2.35 or 2 7/20 square foot.
I hope this helps.
YOU'RE WELCOME :D
