Answer:
B. 
Step-by-step explanation:
Given:
A spherical ball just fits inside a cylindrical can, 20 centimeters tall, with a diameter of 20 centimeters.
diameter of Sphere = 20 centimeters
hence radius = half of diameter = 
Hence we need to find the volume of sphere.
Volume of sphere = 
Here r is the radius of the circle.
Hence Volume of sphere =
Hence Option B is the correct answer.
For this case we have that the generic equation of the line is given by:
Where,
m: slope of the line
b: intersection with the y axis.
Since the line is parallel to PQ, then the slopes are equal.
We have then:
On the other hand we have:
Substituting values we have:
Answer:
The equation of the line that is parallel to line PQ and that has the and intercept b = -3 is:
Answer:
