Step-by-step explanation:
Step by step
1: A = pi * r^2
2: A = 3.14 * 25
In words.
1: Times the pi by r^2
2: The answer will come out as 3.14
3: Times the Answer that is 3.14 by 25
Answer: A= 78.5 sq. in

Answer:
He has written about 100 times as many words.
Step-by-step explanation:
In order to find this, we first need to find the number that he has written this month. In order to do so, we need to subtract the previous month from the current total.
12,580 - 125 = 12,455
Now that we have that number, we can divide it by the previous month to see how many times more words he wrote in the second month.
12,455/125 = 99.64 times more, or rounded, about 100 times more.

Step-by-step explanation:
4x - 5y = -12
-x + 5y = 18
Add the equations together:
4x + -x = 3x
-5y + 5y = 0
-12 + 18 = 6
So now you have:
3x = 6
Divide both sides by 3:
X = 2
Now you have the value of x, replace x with 2 in one of the equations and solve for y:
4(2) -5y = -12
8 -5y = -12
Subtract 8 from both sides:
-5y = -20
Divide both sides by -5:
Y = 4
The solution is x = 2 and y = 4 which is written as (2,4)
