A plumbers plastic pipe is 4 m long, has an inside diameter of 4.0 cm and an outside diameter of 5.0cm. What is the volume of th

SCORPION-xisa [38]

Answer: $V=0.0028278\ m^3$

Step-by-step explanation:

Given

Length of the pipe $l=4\ m$

Inside diameter of the pipe $d_i=4\ cm$

Outside diameter of the pipe $d_o=5\ cm$

Volume of the pipe

$\Rightarrow V=\dfrac{\pi }{4}[d_o^2-d_i^2]\\\\\text{Insert the values}\\\\\Rightarrow V=\dfrac{\pi}{4}[5^2-4^2]\times 10^{-4}\times 4\\\\\Rightarrow V=28.278\times 10^{-4}\ m^3\\\\\Rightarrow V=0.0028278\ m^3$

Factor using the identity: a3 + b3 = (a + b)(a2 – ab + b2) 8z3 + 27

vivado [14]

Answer: this is our required factor i.e.

$8z^3+27=(2z+3)(4z^2-6z+9)$

Explanation:

Since we have given that

$8z^3+27$

As we know the identity , which says that

$a^3+b^3=(a+b)(a^2-ab+b^2)$

So, we can use this here ,

$8z^3+27=(2z)^3+3^3\\\\=(2z+3)((2z)^2-2z\times 3+3^2)\\\\=(2z+3)(4z^2-6z+9)$

Hence this is our required factor i.e.

$8z^3+27=(2z+3)(4z^2-6z+9)$
