Answer: $12,723.45
Step-by-step explanation:
Details of each play area :
The radius of circle = 18 feet long
Cost of fake grass per square foot = $12.50
Therefore,
We can obtain the Area of the play area by calculating the area of the circle:
Area of a circle = πr^2
Area = π × 18^2
Area = 1,017.876ft^2
Since the cost per square foot is $12.50
Therefore, Cost of 1,017.876 ft^2 equals
Cost per square foot × Area of play area
($12.50 × 1,017.876)
= $12,723.45
Answer:


Step-by-step explanation:
∠1 and ∠2 are vertical angles.
∠1 = ∠2
<u>Part A:</u>
<u></u>
Create an equation and solve for x.
20x + 21 = 30x - 29
Add 29 and -20x on both sides.
20x + 21 + 29 - 20x = 30x - 29 + 29 - 20x
Simplify the equation.
50 = 10x
Divide both sides by 10.
= 
Simplify the equation.
5 = x
Switch sides.
x = 5
<u>Part B:</u>
<u></u>
Let x = 5
20(5) + 21
Distribute.
100 + 21
Add.
= 121
Since both angles are vertical angles, they are equal.
∠1 = 121°
∠2 = 121°
