Using Communative Property, We can switch the equation around to make it look the same.
We calculate for the volumes of each of the wax needed for the candles through the equations presented below.
For cylinder:
V = πr²h
where V is volume, r is radius and h is height.
Substituting the known values,
V = (3.14)(3 in)²(6 in)
V = 169.56 in³
For sphere:
V = 4πr³/3
Substituting the known values,
V = 4(3.14)(3 in)³ / 3 = 113.04 in³
The difference between the two volumes,
difference of volumes = 169.56 in³ - 113.04 in³
<em>difference of volumes = 56.52 in³</em>
Thus, the answer to this item is the last choice.
Answer:
The answer will be D. 145
Step-by-step explanation:
Because I said so
Answer:
The answer is : b) a confound
Step-by-step explanation:
While manipulating, is possible that some factors like noise in the hall, can affect learning in one of the groups but not in the other.
This possibility reflects the presence of a confound.
We can define a confounding variable as an external influencing factor which results in bringing changes in the effects of a dependent and independent variable.
This variable changes the outcome of an experiment and produces useless results.
