The answer to this stuff I hate math please help

Answer:
....sorry
Step-by-step explanation:
for the second one, remember LW=are for fiding the area of the base,
for cone, base=circle, so therfor V=HB/3, and B=circle=pir^2, so V=(1/3)(hpir^2)
h=17
r=6
V=(1/3)(17(3.14)6^2)
V=17(3.14)12
V=640.56
rond tenth
V=640
