Answer:
oooooof
Step-by-step explanation:
First, multiply both sides by y to get rid of that y in the denominator.
![y(\frac{3}{2} y)= y( \frac{16}{y} + 2) ](https://tex.z-dn.net/?f=%20y%28%5Cfrac%7B3%7D%7B2%7D%20y%29%3D%20y%28%20%5Cfrac%7B16%7D%7By%7D%20%2B%202%29%0A)
![\frac{3}{2}y^2= 16+2y](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B2%7Dy%5E2%3D%2016%2B2y%20)
Then, rearrange it to put it into standard form so you can easily see the values for a, b, and c.
![\frac{3}{2}y^2 +2y +16=0](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7Dy%5E2%20%2B2y%20%2B16%3D0)
Plug into quadratic formula, and you get this result:
![y= \frac{2+/- \sqrt{100} }{3}](https://tex.z-dn.net/?f=y%3D%20%5Cfrac%7B2%2B%2F-%20%5Csqrt%7B100%7D%20%7D%7B3%7D%20)
So, y=4, y=8/3
The answer is 60 because it can be divided by all three numbers. Next time you come across problems such as these, I suggest you start by looking at the number that makes sense logically. For instance, numbers that have 5 as a factor must end with 0 or 5, narrowing the options down to 65 and 60. Since 65 is an odd number, the answer can only be 60.
Answer:
Diameter: 26cm
Circumference: 26π / 81.68cm
Area: 169π / 531cm²
Step-by-step explanation:
Diameter is radius x 2, so 13 x 2 = 26
Circumference is diameter x π, so 26 x π = 26π / 81.68cm
Area is π x r², so π x 13² = 169π / 531cm²
