Answer:
$90.00
Step-by-step explanation:
40% of What is 36?
40/4 = 10 (10%)
36/4 = 9 (9 is 10% of the answer we are looking for)
Multiply both answers (9 and 10) by each other.
You get 90
180
12x15=180
The answer is: 2-6x+3x
Area of Large Circle = 380.13
Area of Small Circle = 254.47
Area of Sidewalk = 125.66
The side walk is just subtracting the smaller number from the bigger one.
The area is just Pi*r^2
