On a part-time job, you are asked to bring a cylindrical iron rod of length 85.8 cm and diameter 2.85 cm from a storage room to a machinist. Will you need a cart? (To answer, calculate the weight of the rod.)

  probably not

Step-by-step explanation:

The volume of the cylindrical shape is ...

  V = πr²h = π(2.85 cm/2)²(85.8 cm) ≈ 547.35 cm³

The density of iron is reportedly about 7.874 g/cm³, so the mass of the iron rod is about ...

  (547.35 cm³)(7.874 g/cm³) ≈ 4294.8 g ≈ 4.3 kg

This is approximately 9.5 pounds, which should be well within your capacity for carrying objects.

No cart should be necessary.

36 is the final answer! : )

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
