Answer:
12.56 feet
Step-by-step explanation:
The perimeter of a shape is the sum of all its side.
Since circle doesn't have "sides", the perimeter is the length of the whole circle. This has the name "circumference".
The circumference of a circle has the formula:
![C=2\pi r](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r)
Where
C is the circumference (perimeter of a circle)
r is the radius
Given,
r = 2 feet
We substitute and find the circumference, using 3.14 as
,
![C=2\pi r\\C=2(3.14) (2)\\C=12.56](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r%5C%5CC%3D2%283.14%29%20%282%29%5C%5CC%3D12.56)
Hence, the circumference is 12.56 feet

I just answered that. how often did you put that in ?
Answer:
![\frac{20-3x}{4x}](https://tex.z-dn.net/?f=%5Cfrac%7B20-3x%7D%7B4x%7D)
Step-by-step explanation:
-This is an LCM problem.
-To simplify, we introduce a least common multiplier which is equivalent the product of the denominators:
![LCM=x\times 4\\\\=4x](https://tex.z-dn.net/?f=LCM%3Dx%5Ctimes%204%5C%5C%5C%5C%3D4x)
#We introduce the LCM and adjust the fractions based on it :
![=\frac{5}{x}+\frac{3}{4}\\\\\\=\frac{20}{4x}+\frac{3x}{4x}\\\\\\=\frac{20-3x}{4x}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B5%7D%7Bx%7D%2B%5Cfrac%7B3%7D%7B4%7D%5C%5C%5C%5C%5C%5C%3D%5Cfrac%7B20%7D%7B4x%7D%2B%5Cfrac%7B3x%7D%7B4x%7D%5C%5C%5C%5C%5C%5C%3D%5Cfrac%7B20-3x%7D%7B4x%7D)
Hence, the simplified form of the fraction is: ![\frac{20-3x}{4x}](https://tex.z-dn.net/?f=%5Cfrac%7B20-3x%7D%7B4x%7D)
Answer:
the volume is 60 cm cubed
Step-by-step explanation:
(5 x 8) / 2 x 3
5 x 8 = 40
40 / 2 = 20
20 x 3 = 60
