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:
x = 5
Step-by-step explanation:
A by B is simply 
3 by x + 1 is 
5 by 2x is 
So, the equality is ;
=
Cross multiply and solve the inequality;
3(2x) = 5(x + 1)
6x = 5x + 5
6x -5x = 5
x = 5
The slope is x , the y is 2

Answer:
6x+8y = 3
Step-by-step explanation:
we have 3x + 4y = 7
4y = -3x + 7
y = -3/4 x + 7/4
so slope is -3/4
2 parallel lines always have same slope
so the slope of our new line is -3/4
so y = -3/4 x + C
for c,
we have (x,y) = (-2/3,7/8)
7/8 = -3/4 * -2/3 + C
C = 3/8
so equation is
y = -3/4 x + 3/8
simplyfyig,
8y = -6x + 3
or, 6x+8y = 3
