Answer:
Probability that, of the questions studied, all three were the test questions selected by the professor is 0.05
Step-by-step explanation:
Total question gives by teacher = 6
A student has time to study for only three of these six questions.
We are supposed to find the probability that, of the questions studied, all three were the test questions selected by the professor?
So, Probability that, of the questions studied, all three were the test questions selected by the professor =
=
=
Hence Probability that, of the questions studied, all three were the test questions selected by the professor is 0.05
To get the surface area of the sphere, we need to know the radius. Since the volume is given, we can get the radius.
Volume =
π r³
5000πm³ =
π r³
5000m³ =
r³
5000m³ x 3 = 4r³
=
<span>
</span>∛3750 = ∛r³
r = 15.536m
r = 15.54m
Since the radius is now known, substitute it directly to the surface area formula
A = 4π x r²
A = 4π x (15.54)²
A= 3,034.67 m² or 3,035 m²
The area of the circle is πr², ie. 144π.
The volume of the cilinder is 12×144π = 1728π cm³.
