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
The perimeter is 17 the area is 160
(9 - 4i)(2 + 5i)
To solve this question you must FOIL (First, Outside, Inside, Last) like so
First:
(9 - 4i)(2 + 5i)
9 * 2
18
Outside:
(9 - 4i)(2 + 5i)
9 * 5i
45i
Inside:
(9 - 4i)(2 + 5i)
-4i * 2
-8i
Last:
(9 - 4i)(2 + 5i)
-4i * 5i
-20i²
Now combine all the products of the FOIL together like so...
18 + 45i - 8i - 20i²
***Note that i² = -1; In this case that means -20i² = 20
18 + 45i - 8i + 20
Combine like terms:
38 - 37i
^^^This is your answer
Hope this helped!
