Answer:

A =45216 miles^2

Step-by-step explanation:

We can find the radius

C = 2 * pi *r

754 = 2 * pi *r

Divide each side by 2 pi

754 /2pi = 2 * pi *r/ 2 pi

377/pi =r

Approximating 3.14 for pi and rounding the radius to the nearest mile

120 = r

Now we need to find the area

A = pi r^2

A = 3.14 (120)^2

A = 3.14 (14400)

A =45216 miles^2

Solve y=34x y=-54x+52

jeyben [28]

Answer:

x= 13/22

Step-by-step explanation:

you can substitute y= 34 x on the second equation

34x = -54x +52 add 54x to both sides

34x +54x = -54x +54x +52

88x = 52 divide both side by 4

22x = 13 divide both sides by 22

x= 13/22
