Step-by-step explanation:
hello :
4lnx - 8 = 12
4lnx - 8 +8= 12+8
4lnx =20
lnx =5
coclusion : x =e^5
A. x = 148.4
-2√20 - √125
(first make radical into simplest form - make sure to get similar radical)
√20 = 4√5
√125 = 5√5
(subtract the common radicals together)
-4√5 - 5√5 = -9√5
-9√5 is your answer
hope this helps
(Pi* r^2) = the area of the circle, or cross section
= 201.06
Multiply by the height for volume, *12
= 2412.74 -- this is the total volume
now *2/3 to get the answer
=1608.5
I dont know what the units are, they aren't given
