trapecia [35]

Answer: $2514.28\ cm^3$

Step-by-step explanation:

Given

The height of the cylinder is $h=8\ cm$

Circumference of the base is $20\pi \ cm$

suppose 'r' is the radius of the cylinder

$\Rightarrow 2\pi r=20\pi\\\Rightarrow r=10\ cm$

The volume of a cylinder is $V=\pi r^2h$

$\Rightarrow V=\pi \times 10^2\times 8=2514.28\ cm^3$

A 1 km long train travelling at a speed of 60km/h enter a tunnel 1km long. What time will the train take to come out of the tunn

zysi [14]

Answer:

2 minutes

Step-by-step explanation:

The front of the train enters the tunnel and travels 1 km before the rear of the train enters the tunnel. Thus, the total distance traveled by the front of the train is 2 km, and this is covered in a certain number of hours:

Since distance = rate times time, time = distance / rate. In this particular case we have:

2 km

time = distance / rate = ------------------- = (1/30) hr

60 km/hr

(1/30) hr converts to 2 minutes, since 1 hr = 60 minutes

consider the exponential function g(x)=100 x (2). which of the following situations could be modeled by the function?

daser333 [38]

The initial value of 100 that doubles over each interval.
without the answer choices, I can only describe it and give you an example of the graph.
I'm assuming the function is 100*(2)^x because if it is as listed it would be a quadratic function with a vertical stretch of 100.

Name the algebraic property demonstrated in the example below.

VikaD [51]

The algebraic expression x • y • z = y • x • z exhibits the transitive property. Transitive property is applied when rearranging the elements or numbers within a term such that the answer or value is still the same. Transitive property is useful in factoring procedure.
