first is cone
2nd is half circle aka hemisphere
V of cone=(1/3)hpir^2
V of hemisphere=(1/2)(4/3)pir^3=(2/3)pir^3
first, cone
d/2=r
10/2=5=r
h=15
cone=(1/3)(15)pi5^2
cone=5pi25
cone=125pi
hemisphere=(2/3)pir^3
r=5.5
V=(2/3)pi5.5^3
V=(2/3)pi166.375
V=110.9166666666pi
which is bigger
125pi or 110.9166666666pi
125 pi is bigger aka the conical container
how much bigger
125pi-110.9166666666666pi=14.083333333333pi
aprox pi=3.14
difference is 44.221666666
round
44 gallons
pick the first one (concal)
holds aprox 44 more gallons
