The U in the upper right corner stands for the universal set.
As universal set defined the set containing all objects or elements and of which all other sets are subsets. So, the answer is B.
The volume of the partial cone is the volume of the entire funnel minus the volume of the cylindrical part.
The volume of a cylinder is given by:

where: r is the radius of the cylinder and h is the height of the cylinder.
Given that the cylindrical part of the funnel has a height of 1.5 cm and a diameter of 1.5 cm, thus the radius is 1.5 / 2 = 0.75 cm and the volume is given by:

Therefore, the volume of the partial cone is given by 16.59375 - 2.65072 = 13.94303 cubic cm.
Answer:
B. 6
Step-by-step explanation:
you just have to divide 36 by all of the options. and you will get 6
Since the denominator cannot be zero, you can set 4z+1=0 to find the excluded values.
4z+1=0
4z=-1
z=-1/4
And thus, z cannot equal -1/4
