Answer: D
Ok find circumference sinc that is what touches the grownd
C=pid
d=2.5
c=2.5pift
aprox pi=3.14 for problem
c=2.5(3.14)
c=7.85ft
how many 7.85ft does it take to get 5280 ft
7.85 times how many=5280
divide both sides by 7.85
how many=672.611
tenth
672.6
answer is 672.6revolutions

Answer:
x = 14.25
Step-by-step explanation:
7(x-9)=3(x-2)
Follow the distributive property
7x - 63 = 3x - 6
Add 63 to both sides
7x = 3x + 57
Subtract 3x from both sides
4x = 57
Divide both sides by 4
x = 14.25
