The circumference of a circle is C=2πR, where R is the radius of the circle and π≈3.14.
So if we open the circumference of the circle into a straight line segment, the length of this segment is C=2πR≈2*3.14*R=6.28R
4 rotations mean 4 circumferences that is 4 segments of length 6.28R,
which makes a linear distance of 4*6.28R=25.12R
i: the radius of the smaller wheel is R=r, thus it covers a distance of 25.12r feet
ii: the radius of the smaller wheel is R=2r, thus it covers a distance of 25.12*2r=50.24r (feet)
50.24r is twice 25.12r, thus the larger wheel traveled Twice the distance of the smaller one.
Answer: the larger covered twice the distance of the smaller.

Answer:
63‾√2
Step-by-step explanation:
Answer:
"Ratio
" seems to be the appropriate choice.
Step-by-step explanation:
- A scale that is being used to mark quantities with a regular process or order, a quantifiable significance discrepancy, as well as a "true zero" value.
- Any factors that should be considered on something like a ratio scale which can be calculated usually involve:
Height: Should be represented in inches, centimeters, feet, respectively., and therefore can't be smaller than 0 (zero).
The measure of angle APQ should be 90 degrees considering all the angles in a square add up to 360 degrees. NPQ should also be 90 degrees
