Step-by-step explanation:
First, you have to find the arc length of the sector. To do that, use the formula for arc length.
Since the figure is a semicircle, we know the central angle is 180, so plug that in for x. We also know the diameter, which is 5. So plug that in for d. Once you get the arc length, add 5 to it. 5 is the diameter and is part of the perimeter
Hello.
For all dilution problems use the dilution equation:
<span>C1V1 = C2V2 </span>
<span>20*V1 = 6*55 </span>
<span>V1 = 6*55/20 </span>
<span>V1 = 16.5 gallons </span>
<span>The final volume must be 16.5 gallons </span>
<span>You must add 16.5 - 6 = 10.5 gallons water to be added.

Have a nice day
The answer is $85.50
57 x 50% or 57 x .5 = 28.50
Add $28.50 to $57 and you get $85.50
