Answer:
B is the answer
Step-by-step explanation:
A = πr²
24π = πr²
24 = r²
24 = r²
= r
r = 
= 2
C = 2πr
C = 2π(2
)
C = 4
π
Y=-3/2x+4
The slope is -3/2, since Kerry traveled three feet and only went down 2.
The y intercept is 4, since she started four feet above the origin
Make a proportion:

Then cross multiply and divide to solve.
20x=119
x=5.95
The answer is $5.95
Simplify
2/4z + 1 = 2/4z + 1
Answer: D. Infinite solutions
