we know that
[volume of a cylinder]=pi*r²*h
so
[volume of the half cylinder]=pi*r²*h/2
r=10/2-----> r=5 in
h=12 in
[volume of the half cylinder]=pi*5²*12/2----> 150*pi in³

the answer is
150*pi in3

pi*r²*h
pi*r²*h/2
r=10/2-----> r=5 in
h=12 in
=pi*5²*12/2----> 150*pi in³

so finally the correct answer would be the first option 
150*pi in3
