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
Answer:
18/3=6 which means the hot air balloon travels 6 miles per hour
6*(3/4)=4 and 1/2 miles
Answer:
x=4
Step-by-step explanation:
Consider ΔKLJ:
sinθ=opposite/hypotenuse
sin30=LJ/8√2
LJ=0.5*8√2=4√2
Consider ΔMLJ:
sinθ=opp/hyp
sin45=x/4√2
1/√2=x/4√2
4√2/√2=x
x=4
This is easy, hint, you multiply ;-;
we know that
The density is equal to the formula
in this problem we have
<u>Find the volume of a piece of green jade</u>
Substitute the values in the formula of density
therefore
<u>the answer is</u>
