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.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
