a graduated cylinder is filled to 41.5 mL with water and a piece of granite is placed in the cylinder, displacing the level to 4
Maksim231197 [3]

Answer:

The answer is

<h2>6.1 cm³</h2>

Explanation:

To find the volume in cm³ we must first find the volume of the rock .

To find the volume of the rock , subtract the initial volume of water from the final volume of the water when the rock was dropped in it

That's

volume = final volume of water - initial volume of water

volume of rock = 47.6 mL - 41.5 mL

= 6.1 mL

Next we use the conversion

<h3>1 mL = 1 cm³</h3>

If 1 mL = 1 cm³

Then 6.1 mL = 6.1 cm³

Hope this helps you

An object was measured by a worker as 17.4cm long, however, the manufacturer specifications list the length of the object at 17.
Olin [163]

Answer:

Percent error = 2.8

Explanation:

Given data;

Actual value = 17.9 cm

Measured value = 17.4 cm

Percent error = ?

Solution:

Formula:

Percent error = [actual value - measured value / actual value] × 100

Now we will put the values in formula:

Percent error = [17.9 cm - 17.4 cm / 17.9 cm] × 100

Percent error = [0.5 cm /17.9 cm] × 100

Percent error = 0.028  × 100

Percent error = 2.8
