Answer: 1/4
Step-by-step explanation: 20 is a fourth of 80
Please mark brainleist if I got it right. I really need it to level up
I think you just divide the 130 ft by the 40 ft = 3.25 ??
Answer:
D. The work shown above is correct, and ![y^5\sqrt[4]{y^3}](https://tex.z-dn.net/?f=y%5E5%5Csqrt%5B4%5D%7By%5E3%7D)
may not be simplified further.
Step-by-step explanation:
If you add all the exponents of y in first line then we get
4+4+4+4+4+3=23
Which is same as the exponent in original problem.
So first line is good.
Since it is 4th root so each 
will turn into y when it moves out of the radical so final answer is correct.
Hence correct choice is "D. The work shown above is correct, and may not be simplified further." is the correct answer.
Diameter is 9 inch so the radius is 9/2=4.5inch
Part A: 2πr=28.26inch
π=28.26/(2r)
π=28.26/(2*4.5)=3.14
Part B: πr^2=63.585inch
π=63.585inch/(4.5inch)^2
π=3.139753086
Part C: Both of the answers are correct but Part B is more percise because it has more significant figures.
