First you need to solve for x by subtracting 9 from both sides (-3x less than/equal to 6), then dividing the inequality by -3, which would also flip the sign, so to speak. now you would have x is greater than/ equal to -2. now you would draw a circle above -2, fill it in since it is equal to, and draw the arrow going toward 0 (I think)
Vcylinder-vcone=vair
vcylinder=hpir^2
vcone=(1/3)hpir^2
vcylinder=16*pi*5^2=400pi
vcone=(1/3)12*pi*4^2=64pi
vylinder-cone=400pi-64pi=336pi
volume is 336pi cubic centimeters or aprox 1055.5 cubic cm
