9514 1404 393

Answer:

  5.1 cm²

Step-by-step explanation:

The area of a segment is given by the formula ...

  A = 1/2r²(α -sin(α)) . . . . . where α is the central angle in radians

For this segment, its area is ...

  A = 1/2(6 cm)²(7π/18 -sin(70°)) ≈ 5.077 cm²

The area of the segment is about 5.1 square centimeters.

_____

The angle is converted to radians by multiplying by π/180°. Then a 70° angle is π(70°/180°) = 7π/18 radians.

74$ for working 6 hours.what is the hourly pay rate in hours per dollar
fgiga [73]

Answer:

.081 hours per dollar

$12.333 dollars per hour

Step-by-step explanation:

I'm a bit confused whether you just want hours per dollar or also dollars per hour, so I'll answer both.

First, for the dollars per hour, you want to do 74 divided by 6 equals 12 1/3. So each hour you get paid $12.333

Fort the hours per dollar, you do 6 divided by 74 equals .081.

River C is 200 miles longer than River D. If the sum of their lengths is 5580 ​miles, what is the length of each​ river?
Valentin [98]

Yo sup??

Let the length of river D be x

then the lenght of river C will be 200+x

but,

lenght of river C+lenght of river D=5580

x+x+200=5580

2x=5380

x=2690

Therefore lenght of river D is 2690 and that of C is 2890

Hope this helps
