A = r² π
254.469 = r² π
r² = 254.469 : 3.14159
r² = 81.00866
r = 9.0048
C = 2 r π = 2 * 9.0048 * 3.14159 = 56.55 units
Basically, from what i can see and understand, is that you take the original price. lets use the chair.
$139.99 you choose which discount you would like to use either the $20 off or 20% off.
if you choose $20 then
$139.99-$20=119.99
but if you choose 20%
$139.99x0.20=27.99 (meaning you deduct $27.99 from $139.99)
139.99-27.99=$112
now you decide which one you'd choose. i would say 20% off because it costs less.

Answer:
Ethan can type 12 pages before the meeting starts.
Step-by-step explanation:
Given:
Number of pages he can type =2
Number of hours he can type 2 pages = 
We need to find number of pages he can type in 
Solution:
Now first we will find number of pages in 1 hour
So we can say;
In = 2 pages
In 1 hour = number of pages he can type in 1 hour
By Using Unitary method we get;
number of pages he can type in 1 hour = 
Now we can say that;
In 1 hour = 16 pages
So = number of pages he can type in
Again By using Unitary method we get;
number of pages he can type in = 
Hence Ethan can type 12 pages before the meeting starts.
Answer:
x = 13
Step-by-step explanation:
If 221 is divided by 17, 13 is the answer.
Since both terms are perfect squares, factor using the difference of squares formula,
a² − b² = (a + b) (a − b) where a = 5(x + 5/4) and b = 4 (x (7/4) ).
− (12x + 25/4) (2x + −25/4)
