<span> Circumference of the tire:</span>

<span> PI x diameter = 3.14 x 26 = 81.6814 Round to 81.68</span>

Speed of the car in inches per minute:

46*5280*12/60 = 48576 inches per minute

48576/81.68 = 594.711

<span> Round to 594.71 revolutions per minute</span>

Does someone mind helping me with this? Thank you!

\qquad\qquad\huge\underline{{\sf Answer}}

The given two polygons are similar to one another ~

Sides of the given polygons are in ratio of :

\qquad \sf  \dashrightarrow \: 28 : 4

to put in simple Ratio ~

\qquad \sf  \dashrightarrow \: 7: 1

So, the sides of the larger polygon are :

  • 4 × 7 = 28

  • 6 × 7 = 42

  • 3 × 7 = 21

  • 4 × 7 = 28

  • 7 × 7 = 49

  • 3 × 7 = 21

  • 3 × 7 = 21

  • 4 × 7 = 28

Now, to find the Perimeter of larger polygon ~ add the side length of all sides :

\qquad \sf  \dashrightarrow \:p = 28 + 42 + 21 + 28 + 49 + 21 + 21 + 28

\qquad \sf  \dashrightarrow \:238 \:  \: units
