Question

a steel pipe is 35 cm long and its external diameter is 10 cm. If the thickness of the pipe is 2 cm and steel weighs 6 g per cm cube, find the weight of the pipe.​

Answer 1

$\huge hlo \: mate$

Firstly, find the volume of the pipe.

πh(R+r) (R-r)

35*22/7*(5+3)(5-3)

=5*22*8*2

=1760cm^3

1cm^3 weighs 6 gram

1760cm^3 would weigh=1760*6 =10560gmcm^3

0.0

Answer 2

Answer:

Step-by-step explanation:

Steel pipe is a cylinder as we know

So the radius of the pipe is 5cm and height is 35cm

Since Thickness is 2cm

And therefore the internal radius is 5-2=3

We need to calculate the volume of pipe's thickness

So formula is πh(R²-r²)

22/7*35(5²-3²)

22*5(25-9)

22*5*16

1760

So the mass of the pipe will be

6*1760=10560Grams or 1.056kg
