a.
This question is a rather odd way to ask you to find the radius of a circle from its area.
A = π r²
40000 = π r²
r² = 40000/π
r = √(40000/π)
r ≈ 112.8379
Answer: 113 miles
b.
C = 2 π r
754 = 2 π r
r = 754/2π = 377/π
A = π r² = A = π (377/π)² = 377²/π
A ≈ 45241.0658
Answer: 45241 square miles
Answer:
17m
(Anyone can correct me if I'm wrong)
Step-by-step explanation:
The following equation would be used: 
We would simply substitute the given values, move the values around then we would get our answer:

Answer:
distance driven < 300 miles.
Step-by-step explanation:
Plan A
She needs the car for 3 days.
1 day costs 60 dollars
3 days cost 60*3 = 180 So this is the maximum amount that she can spend
Plan B
She still needs the car for 3 days
1 day costs 20 dollars of the car does not move
3 days costs 3*20 = 60 dollars.
60 + 0.4m < 180 Subtract 60
0.4m < 180 - 60
0.4m < 120 Divide by 0.4
m < 120/ 0.4
m < 300
Answer
so she should drive less than 300 miles.
A secant line always contains a chord.
