Which Unit Measure would be appropriate for the volume of a cylinder that is 8 meters tall and has a radius of 4 meters?
2 answers:
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Radius of cylinder = 4 meters
Height of cylinder = 8 meters
We need to find the volume of cylinder.
As we know the formula for "Volume of cylinder ":
As we can see that while calculating volume we consider radius two times and height one time.
So, it has 3 dimensions or units.
So, Unit measure of volume should be in cubic and both the dimensions are given in meters.
Hence, Unit measure of volume is cubic meters.
Thus, Option 'D' is correct.

The game is not fair as 6 times the expected sum is less than the cost, $43.
In the question, we are asked if the game is fair.
For the game to be fair, 6 times the expected sum for the pair from the game has to be greater than or equal to $43, that is,
6E(X) ≥ 43.
The expected sum for the pair, E(X) can be calculated using the formula,
E(X) = ∑x.p(x),
or, E(X) = 1/18 + 1/6 + 1/3 + 5/9 + 1/6 + 7/9 + 10/9 + 1 + 5/6 + 11/18 + 1/3,
or, E(X) = 107/18.
Now, 6E(X) = 6*(107/18) = 107/3 = 35.67.
Since, the total return from the game is $35.67, which is less than the cost of $43, the game is not fair.
