1.) Find the area of the circle:
• Formula: A=pi•r^2
- To find the area of a circle, we need to have the radius, and since the diameter is 2x the length of the radius, the radius is 1/2 of the diameter.
Finding the radius: r=d/2
r=12/2
r = 6.
- Now that we know that r=6, we can substitute it into the formula:
• A=pi•r^2
A=pi•(6)^2
A=113.097
- The area of the circle is 113.097ft.^2. We know that a square foot is $10.50. So, we have 113.097 square feet at $10.50/sq. foot. This means that we will add $10.50 113.097 times. Therefore:
113.097 • 10.50 = 1,187.518
So, total, it will cost $1,187.518

So first thing we have to realise is that we have to make them have equal denominators. So,
.
Now order the fractions....so,
Now we can see why 
is greater than 
but less than 
Answer:
The y coordinate of the shape would be 7 more than its original value.
Step-by-step explanation:
Answer: yerror she made is at the level of the first step if you want me to show it to you ask me in comment
The amount eroded at millimetre per hour is 0.002283
In order to determine the answer, take the following steps :
1. determine how many hours are in a year
there are 24 hours in a day
There are 365 days in a year
Number of hours in a year = number of days in a year x number of hours in a day
24 x 365 = 8760 hours
2. convert centimetre to millimetre
1 cm = 10mm
2cm x 10 = 20mm
3. Amount eroded per hour in millimetres = amount eroded per year / total number of hours in a year
20 / 8760 = 0.002283 millimetre / hour
