V = Bh
B = area of base = pi * r^2 = 3.14 * 4^2 = 3.14 * 16 = 50.24
h = 6
V = Bh = 50.24 * 6 = 301.44 = 301 in^3

volume = pi*r^2*h
Look at it this way, first you calculate the area for the circle base, then you multiply that by the height for the volume.
So
Area=(3.14)*4^2=50.24 square inches
then
volume=area*height
volume=50.24*6
volume =301.44 cubic inches
.
