P= 278, because 2(68)=136 and 2(71)=142, so just add them together to get the answer.
D. 2 radians
Remember that: Radian=arc length/radius
In your case you have
arc length=2r
radius=r
so Radian=2r/r=2
0.78p = 2.73.....with p being the number of lbs
divide both sides by 0.78
p = 2.73 / 0.78
p = 3.5 lbs <=== ur answer
Hey there!
The answer to your question is, yes, it is
Given:

To see if they are equal, we can use cross products (see below for information about this, if you don't know what it is). Let us assume they are equal. This would mean that:

Let's solve it and see if it is true:


Therefore, they <em>are </em>proportional.
