Answer:
(d) All of the above
Step-by-step explanation:
In order to solve this question we will have to find out which numbers are located in which group (the group of numbers are U, B, B').
So lets start of with finding out what numbers are a part of group U. By looking at that picture we can see that all number on the graph are a part of group U. So.....
U = {0,1,2,3,4,5,6,7,8,9}
Then we can find out what numbers are part of the group B. We just have to include the numbers that are located within the circle and exclude all of the numbers out side of the circle. So........
B = {0,1,4,5,6,7,8}
We find numbers that are parts of group B' by using a similar method that we used to find out what numbers were part of group B (Just this time we include all numbers outside of the circle and exclude all of the numbers inside the circle). So ......
B' = {2,3,9}
Now we see that the right option is option d.
Answer:
3
Step-by-step explanation:
Answer:
C. π(2ft)²(10ft) + 1/3π(2ft)²(13ft-10ft)
Step-by-step explanation:
Given:
diameter = 4ft
length of the cylindrical part = 10ft
entire length of the silo = 13ft
Find the volume of the silo = volume of cylinder and volume of the cone
Formulas:
Volume of cylinder: πr²h
Volume of come: 1/3πr²h
2ft= radius
height =10
volume π×2²×10
radius 2ft
height 13-10=3ft
Volume= 1/3×π×2²×3 cube feet
Therefore the third answer is correct: C. π(2ft)²(10ft) + 1/3π(2ft)²(13ft-10ft)
