<span>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</span>
What you must do for this problem is to re-imagine the equation in "vertex form"
Vertex form:
where "h" shifts the graph to the right if "h" is positive" and to the left if "h" is negative. K shifts the graph up and down.
a=1
h=1
k=0
So, your final answer should be: 
Answer:
From the given figure we can see that :---
MN||PO, MN=PO and MP=NO
Therefore, angle M=angle N (adjacent sides of the trapezoid)
angle M=angle N= (6×18)+20=108+20 =128°
angle O =(180°-128°)=52°
<h3>Hence, angle O is <u>52°</u><u>.</u></h3>

Answer:
If the bag contained 20% of blue marbles and 50% of green marbles than that would mean the bag would contain 30% of red marbles. The probability of picking a red marble from the bag would be considered unlikely.
