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:
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 ,
Hence, the circumference is 12.56 feet
Answer:
a) 97.37%
b) 1.31%
Step-by-step explanation:
a)
Here we want to calculate the area under the Normal curve with mean 0.52 and standard deviation 0.009 between 0.5 and 0.54
This can be easily done with a spreadsheet and we get
<em>P (0.5くV < 0.54) = 0.9737 or 97.37% </em>
(See picture 1)
b)
Here we want the area under the Normal curve with mean 0.52 and standard deviation 0.009 to the left of 0.5.
<em>P(V ≤ 0.5) = 0.0131 or 1.31% </em>
(See picture 2)
