3.142 because if you put pi in a calculator, it will be 3.1425..., ad 3.142 is closer to 3.1425 than 3.141
For question 1, it is important to know the vertical angles are angles that are equal to each other because they are congruent and are "across" from each other when two lines intersect. Therefore, you can set an equation where one side is equal to the other as you are solving for x, which would be 2x=x+30. You may then solve this equation like any other equation based on mathematical properties and operations, whereas this is how you may do question #1.
I'm pretty sure that your answer is B. because your outlier is at 3, so that cancels A. Then there are no skews so that gets rid of C. Last but not least there is an an outlier so that marks out D. leaving you with B. Hope this helps!
Answer:
Step-by-step explanation:
Pressure p = force F/ area A
P = F/A
F = 100N and A = 4m^2
P = 100/4
P = 25N/m^2
Step-by-step explanation:
V= π r^2h

First you need the radius, if the diameter is 10inches divide by 2 = 5 inches, that's your radius.
π(5inches)^2 times (20 inches)
firsr work out 5^2= 5x5= 25
π(25inches) times (20inches)
25x20=500π inches
500π =1,570.7963267948966192313216916397514420985
which rounds to 1,570, the first one is your answer
