The surface area is increased 16 times.
The volume is increased 64 times.
Find volume
volumecone=(1/3)(h)(pi)(r^2)
hemisphere is just a half sphere aka, 1/2 times volume of sphere so
hemisphere=(1/2)(4/3)(pi)(r^3)
fnd their volumes don't evaluate the true value till end, leav pi as pi
(or use pi key for graphing or scientific calculators)
cone
d/2=r
10/2=r=5
h=15
V=(1/3)(15)(pi)(5^2)
V=(5)(pi)(25)
V=125pi
hemisphere
V=(1/2)(4/3)(pi)(5.5^3)
V=(4/6)(pi)(166.375)
V=110.91666666666666666pi
which is bigger
125pi or 110.916666666666666666pi
125 pi
by how much?
125pi-110.91666666666666pi=14.08333333333pi
aprox pi=3.14
14.08333333*3.14=44.2217
rond
44
answer is CONICAL will hold 44 cubic feet more

168
Step-by-step explanation:
None of your answer choices are correct. The answer is 168.
Answer:
Only whole numbers of people, n, are assumed in the calculation.
Step-by-step explanation:
The function relating the number of people, n, to the revenue, r, implicity assumes that only whole people will purchase tickets. 13.5 would mean that 13 normal people and 1/2 of a person bought tickets. This can't be in the domain, since the ticket saleperson would run away if 1/2 of a person showed up: thus no ticket sale.
Actually, it may depend on how one defines a person. Is it 1/2 physically, or 1/2 mentally? I've personally seen the latter show up at some fundraisers.
