Answer:
128°
Step-by-step explanation:

Semicircle perimiter=1/2circumferece+diameteter
diameter=2r
c=2pir
so 1/2circumference=1/2(2pir)=pir
d/2=r
given
d=30
d/2=30/2=15=r
perimiter=pir+d
perimiter=15pi+30
aprox
perimiter=77.1239
total cost=cost per foot times feet
total cost=9.25 times 77.1239
total cost=713.396
it will cost $713.40
