so if they have an answer choice saying he is right then he is.

if not then step two because it could have a negative number instead of a positive

How do i find the volume of a cylinder?

mestny [16]

Hi there! The answer is 226 in^3

Like you've already written it down, the formula of the volume of a cylinder is
$volume \: = \: base \: \times \: height$

Since the base of any cylinder is a circle, we can find the area of this circle with the formula
$a \: = \pi \: {r}^{2}$
With r representing the radius.

Therefore, the volume of any cylinder can be found with the formula
$v \: = \pi \: {r}^{2} \: h$
With h representing the height.

Filling in this formula gives us the following
$v \: = \pi \times {3}^{2} \times 8 = 226.08$
Hence, the volume of this cylinder is about 226 in ^ 3.

I put this but idk how to do it

D ( AC ) = 6 ( because A and C have the same y-coordinate )
d ( AB ) = √[(x2 - x1)² + (y2 - y1)²],
where A ( x1, y1 ) = ( -3, 1 ) and B ( x2, y2 ) = ( -1, 3 )
d ( AB ) = √[(-1 -(-3))² + (3 - 1 )²] = √[(-2)² + 2²] = √8 = 2√2
d ( BC ) = √[(3-(-1))² + (1-3)² =√[4² + (-2)²]= √20 = 2√5
The perimeter of ΔABC:
6 + 2√2 + 2√5 = 6 + 2 · 1.41 + 2 · 2.24 =
= 6 + 2.82 + 4.48 = 13.30

7% of Americans are vegetarians. If you ask a random person whether he or she is a vegetarian, what is the probability that the

ElenaW [278]

This question is flawed. I believe it was meant to ask: "If you ask a random person <span>who identifies as American</span> this question, what is the probability?" etc. Assuming this is the case, it would be 93% probability.

Otherwise, America is equivalent to 4.34% of the total world population as of Thursday, April 6, 2017 (http://www.worldometers.info/world-population/us-population/). So, 7% of 4.34% is 0.3%.

I'd stick to 93%
