Answer:

4.708 feet    

Step-by-step explanation:

Given that: The sector area A=28.25 ft2

The radius r = 12 feet

....attached work below

Now the length of steel (Arc length ) = 2πr/2π × θ

The length of steel (Arc length ) = r × θ

The length of steel (Arc length ) = 12 × 0.39236

The length of steel (Arc length ) = 4.708 feet

Solve the equation and show all work please show steps!!<br> m/9 - 17=21
masya89 [10]
Okay. The question is m/9 - 17 = 21. First off, we will add 17 to both sides. -17 + 17 cancels out. 21 + 17 is 38. That leaves m/9 = 38. Multiply each side by 9 to isolate the m, because m is the numerator and 9 is the denominator. m/9 * 9/1 cancels out. 38 * 9 is 342. Let's check this. 342/9 is 38. 38 - 17 is 21. 21 = 21. There. x = 342.
