Sagot :
[tex] \frac{9/2*9/2*4* \pi }{3} [/tex]
= [tex] \frac{81*3.14 }{3} [/tex]
=27*3.14 (the cone's v)
so multiply 5 to the v = 135*3.14 (cylinder's v)
A:3*3*3*3.14=27*3.14 X
B:5*5*4.23*3.14=105.75*3.14 X
C:6*6*15*3.14=540*3.14 X
D:2*2*33.75*3.14=135*3.14 O
Answer: is .....D

so volume of a cone=1/3 times (area of base) times height
area of base=circle so
1/3 times pi times radius^2 times height
height=4
diameter=2radius
diameter/2=radius
9/2=4.5=radius
height=4
radius=4.5
aprox pi at 3.14
1/3 times (3.14 times 4.5^2) times 4=84.78
that's the volume of the cone
volume of cone=1/5 of cylinder
84.78=1/5cylinder
multiply both sdies by 5
423.9=volume of cylinder
volume of cylinder=height times area of base
area of base=3.14 times r^2
v=h3.14r^2
423.9=3.14hr^2
divide both sdies by 3.14
135=hr^2
since we are not given the specific ratio of height to radius or such to the cone to the cylinder, we must use trial and error to elimninate wrong choices
135=hr^2
let's try A
A
135=3(3^3)
135=3(9)
135=27
false
A is wrong
B
4.23=h 5=r
135=4.23 times 5^2
135=4.23 times 25
135=105.75
false
B is wrong
C
h=15 r=6
135=15 times 6^2
135=15 times 36
135=540
false
C is wrong
D
33.75=h 2=r
135=33.75 times 2^2
135=33.75 times 4
135=135
the answer is D since it fitst the dimentions
area of base=circle so
1/3 times pi times radius^2 times height
height=4
diameter=2radius
diameter/2=radius
9/2=4.5=radius
height=4
radius=4.5
aprox pi at 3.14
1/3 times (3.14 times 4.5^2) times 4=84.78
that's the volume of the cone
volume of cone=1/5 of cylinder
84.78=1/5cylinder
multiply both sdies by 5
423.9=volume of cylinder
volume of cylinder=height times area of base
area of base=3.14 times r^2
v=h3.14r^2
423.9=3.14hr^2

D
33.75=h 2=r
135=33.75 times 2^2
135=33.75 times 4
135=135
the answer is D since it fitst the dimentions
