Answer:
35
Step-by-step explanation:
2x+1=71
71-1=70
70÷2=35
therefore x must be 35
So circumference is the distance around the wheel
that is the part that is actually touching the ground
so therefor the wheele travels 3 inches per rotations
5 rotations per minute
we have to find the distance
3 times (number of roations) times 1 minute=3 times 5 times 1=15
answer is 15 in per miute
I=15
Use the Pythagorean Theorem to find the diagonal of the rectangle.
The diagonal of the rectangle is the diameter of the circle.
Diameter (d) = 2 · radius (r)
Circumference (C) = 2· π · r → π · d
