Answer 2

Find out the weight of the PVC pipe with an outside diameter of 0.82 inches and an inside diameter of 0.75 inches .

To proof

Formula

`volume\ of\ the\ cylinder = \pi r^(2)h`

r = radius , h = height

As given

36 inch piece of PVC pipe with an outside diameter of 0.82 inches and an inside diameter of 0.75 inches.

`outside\ radius = (0.82)/(2)`

= 0.41 inches

`inside\ radius = (0.75)/(2)`

= 0.375 inches

Volume of the PVC pipe = volume of the outside - volume of the inside

put

`\pi = 3.14`

`= \ 3.14*0.41*0.41*36 -\ 3.14*0.375* 0.375*36`

thus solving the above

we get

Volume of the PVC pipe = 3.105 inches³ ( approx)

As given

1 inches = 0.063 pounds

weight of a PVC pipe = 3.105 × 0.063 pounds

= 0.196 pounds (approx)

Hence proved
