Answer:
The area of the quarter circle is ![16\pi\ cm^{2}](https://tex.z-dn.net/?f=16%5Cpi%5C%20cm%5E%7B2%7D)
Step-by-step explanation:
we know that
The area of a quarter circle is equal to
![A=\frac{1}{4}\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B4%7D%5Cpi%20r%5E%7B2%7D)
we have
![r=8\ cm](https://tex.z-dn.net/?f=r%3D8%5C%20cm)
substitute the value
![A=\frac{1}{4}\pi (8)^{2}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B4%7D%5Cpi%20%288%29%5E%7B2%7D)
![A=16\pi\ cm^{2}](https://tex.z-dn.net/?f=A%3D16%5Cpi%5C%20cm%5E%7B2%7D)
How you wrote it is kind of confusing but if I'm reading what you're saying right. There are 2028 . <span />
Answer:
The total compound interest is $3,488.50, I hope I helped explain how to find total compound interest
Step-by-step explanation:
So the formula for this would be:
A = P(1+r/n)^nt
A = the amount of your principal plus interest, which is the total
P = stands for the principal, which is your original amount invested
r = shows the interest rate in decimal form
n = stands for the number of compounding periods
So to solve for the compound interest we would plug in our numbers in replacement for the letters
You subtract 15.50 from 47.50
then you will get your answer it is 31
