Answer:
113.1
Step-by-step explanation:
Write down the equations on the top of your paper; it could help you throughout your homework.
The equation for circumference is 2 times pi, times the radius.
The Radius is the diameter times two.
2 times 9=18, so therefore the radius is 18.
Once you have that done, just put in your calculator 2 times pi times 18.
Check the picture below.
so, to get the area of the triangles, we can simply run a perpendicular line from the top to the base, and end up with a right-triangle with a base of 22 and a hypotenuse of 34, let's find the altitude.

so then the surface area of the triangular prism is,
Answer:
Option B.
Step-by-step explanation:
It is given that
A = {The Rationals}
B = {The Irrationals}
We need to find the set A∪B.
If we have two sets X and Y then union of these sets (X∪Y) contains all the elements of set X, of set Y or both.
It is given that A is the set of rations and B is the set of irrational, so the union A∪B is the combined set of all rational or irrational numbers.
A∪B = {The Rationals} + {The Irrationals}
A∪B = {The Reals}
Therefore, the correct option is B.
