Answer:
21.98
Step-by-step explanation:
first you think about the equation for perimeter. P=d(pi)
then you multiply your radius by 2 and that is 7 so you multiply 7 by pi (3.14)
that is the number of feet. so then you multiply your number of feet by your cost per foot and you get 21.98
1 3/5 = 8/5
.2=2/100
make an equality:
x/(8/5)=2/100
it kinds looks weird on here but write it out on paper
then cross multiply:
100x=(2)(8/5)
100x=16/5
now divide each side by 100:
x=4/125
same for the second one:
make an equality:
x/2=2/100
cross multiply:
100x=(2)(2)
100x=4
x=1/25
