Step-by-step explanation:
To obtain the scale factor, the dimensions must be in the same units.
Using the conversion

scale factor = 5 : 180 ← divide both parts by 5
scale factor = 1 : 36
If it were a complete circle, its circumference would be
(π) x (diameter) = (π) x (2R) = 70 π inches .
Since it's only half of the circle, the length of the curved part is
70 π / 2 = 35 π = <em>109.9 inches</em> .
