This is saying that 200 equals 25%. Set up a proportion like so. Remember that percent means per 100
200/x= 25/100
25*8=200
100*8=800=x
Final answer: 800
A= <span>π (n + 4) ^2
= </span><span>π (n + 4) (n + 4)
remember order of operations FOIL
= π (n^2 + 4n + 4n + 16)
= </span>π (n^2 + 8n + 16)
A= πn^2 + 8πn + 16<span>π
do the same for B just change the signs
B = </span>πn^2 - 8πn + 16<span>π
subtract the two
(</span>πn^2 + 8πn + 16π) - (πn^2 - 8πn + 16<span>π)
=16</span><span>πn</span>

Answer: quadrant 3</h3>
Work Shown:
Divide 1300 over 360
1300/360 = 3.611 approximately
Focus on the whole part 3. There are 3 full revolutions
3*360 = 1080, which subtracts off to get 1300-1080 = 220 left over.
The remainder 220 tells us where the angle points. It's in quadrant 3 since 220 degrees is between 180 degrees and 270 degrees.
Answer:
$38.4
Step-by-step explanation:
20%=0.20
32*0.20=6.4
32+6.4=38.4
