Answer:

The volume of the first is not 2 * volume of the second. They both have the same volume.

Step-by-step explanation:

The 2 cylinders described are identical. The diameter = 2 times the radius, so the radius of the first cylinder = 1/2 * 7 = 3.5 in,  which is the same as the radius of the second one. Also the heights are the same so the volumes are the same too.

When you find the volume of the cylinder you square instead which isn't equal to multiplying so the answer will be more then doubled.

Directions: Read the scenario below and calculate what Marcus' pay is after deductions are
hram777 [196]

Answer:

$346.65

Step-by-step explanation:

If Marcus worked a total of 40 hours, and he earns 10$ an hour, his payment before deductions is 400$, as put in the "gross pay".

We need to sum all the deductions:

9.75 + 3.10 + 30 + 10.5 = 53.35

Now, to know Marcus net pay, we just need to subtract his gross pay from this total deduction:

400 - 53.35 = 346.65

So, his net payment is $346.65
