Answer:
a)B)9π
b)G)16π in²
Step-by-step explanation:
according to the question
![64 \times \frac{\pi}{4}](https://tex.z-dn.net/?f=64%20%5Ctimes%20%20%5Cfrac%7B%5Cpi%7D%7B4%7D%20)
![16\pi \: {in}^{2}](https://tex.z-dn.net/?f=16%5Cpi%20%5C%3A%20%20%7Bin%7D%5E%7B2%7D%20)
as we know
C/d=π
C=dπ
Therefore
C=9π
Answer:
So I believe your just graphing here like a line or bar graph. Look at images in Google for references if needed.
Answer:
y=15
Step-by-step explanation:
The formula for direct variation is
y = kx
5 =k*2
Solve for k
Divide by 2
5/2 = k
y = 5/2 x
Now we substitute x=6
y = 5/2(6)
y = 15
Multiply and divide by the product of the denominators.
