I think: C. 109.9 inches;
Considering that the entire circumference is \(2 \pi r\) a semicircle should be only: \(\pi r=3.14*35=109.9 in\)

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  =  109.9 inches .
