To find the volume of an aluminum cylinder with a mass of 12.4 g and a length of 2.00 cm:
V = π r² L
Density of aluminum is 2.7 g / cm³
Therefore, V = 12.4 g: 2.7 g/cm³ ≈ 5 cm³
5 = 3.14 · r² · 2
r² = 5: 6.28
r² = 0.796
r = √0.796
Thus, the radius of the aluminum cylinder is 0.9 cm.
Answer:
The radius of an aluminum cylinder is 0.9 cm.

lawyer [12517]
The options you provided are unclear to me, so I will respond in general terms: to determine if a point (ordered pair) lies on a line, you need to substitute the x-value from that pair into the line's equation and check if the resulting y-value matches the y-value of the ordered pair. For example, if your line is y = 4/3x + 1/3, we can check if (0, 0) and (2, 3) fit this line. We find that y = 4/3·0 + 1/3 gives us 1/3, which does not equal 0, indicating (0, 0) is not on the line. For (2, 3), substituting yields y = 4/3·2 + 1/3 = 3, meaning (2, 3) is on the line.

Inessa [12570]
The findings are probably not valid since it is improbable that the tires fitted in just one hour on Monday accurately reflect the whole population of tires.Step-by-step explanation: Out of 8 hours, do you truly believe that one hour could stand for all? This is the reason the results are likely invalid (I also participated in the quiz).

x:200

x/200 =.2121212121...

200(x/200) = 200(.2121212121...)

x = 42.4242...

The expectation is that a player would achieve 42 hits over 200 at-bats.
