Step-by-step explanation:

I had this question on my test>>>>>>>>> v=5y+22
HOPE THIS helps
we know that
The conjugate of a complex number is the number with equal real part and imaginary part equal in magnitude but opposite in sign
so
In this problem we have

the conjugate is equal to--------> 
therefore
<u>the answer is the option</u>
10+3i
Answer:
<em>| In Terms of Pi π |
</em>
<em>V = 6000 π m3</em>
<em>-----------------------</em>
<em>or</em>
<em>V = 18840 m3</em>
<em>-----------------------</em>
<em>| In Terms of Pi π | </em>
<em>V = 168 π m</em>
<em>------------------------</em>
<em>or</em>
<em>V = 527.78756580309 m3</em>
