Acubic inch of pvc material weight 0.063 pounds per cubic inch. what’s the weight of a 36 inch piece of pvc pipe with an outside diameter of 0.82 inches and an inside diameter of 0.75 inches?

ANSWER

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

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.

                                = 0.41 inches

                              = 0.375 inches

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

put

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

360 different combinations

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
