Multistep a museum groundskeeper is creating a semicircular statuary garden with a diameter of 30 feet. there will be a fence around the arden. the fencing costs per linear foot. about how much will the $9.25 fencing cost altogether?

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

Sorry can't answer that question
