What is the volume of a 14 in diameter pipe that’s 2156 long?

storchak [24]

Answer:

Step-by-step explanation:

given that diameter of the pipe = 14 inches

radius = 7 inches

Length =2156 inches

Pipe is in the form of a cylinder

Volume of cylinder = pi r^2 h

where r = radius and h = l = 2156

We have to substitute the values of r and h.

Let us take pi as 22/7

= 22/7 (7)(7)(2156)

Cancel out 7 and multiply the remaining 22 ,7 and 2156

=332024 cubic inches

Select the correct answer.

Afina-wow [57]

Answer:

$d)\ \frac{81}{m^{7}}$

Step-by-step explanation:

$(3m^-4)^3(3m^5)$

First, simplify $(3m^{-4})^3$ :

$(3m^{-4})^3\\\\3^3*m^{-4*3}\\\\27m^{-12}$

$27m^{-12}*3m^5\\\\27*3 *m^{-12+5}\\\\81m^{-7}\\\\81*\frac{1}{m^{7}} \\\\\frac{81}{m^{7}}$

Hope this helps!

Answer:

$\boxed{\boxed{\pink{\bf \leadsto It \ will \ take \ 5 hours \ to \ travel \ 300 \ miles. }}}$

<h3>Step-by-step explanation:</h3>

According to Question , a plane travels 120 miles in 2 hours. So here we will use unitary method .

$\bf\implies If \ it \ covers \ 120 \ miles \ in \ 2 \ hours \\\\\bf\implies Then \ one \ mile \ will \ be \ covered \ in \ \dfrac{120}{2} hrs \\\\\bf\implies Hence \ 300 \ miles \ will \ be \ covered \ in \ \dfrac{2}{120}\times 300 hrs = \red{5 \ hours }$

<h3>Hence it will cover 300 miles in 5 hours .</h3>

Here it was a case of direct proportion in which if two things are directly proportional to each other. If one thing thing increases then the value of second also increases. Here if the time increases then the distance also increases
