B.
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
As given in the question, we know that:
The ratio of the area of the circle to the area of the square is π/4
- The formula to find the volume of the cone is:
V = 1/3*the height*the base area
<=> V1 = 1/3*h*π
- The formula to find the volume of the pyramid is:
V2 = 1/3*the height*the base area
<=> V = 1/3*h*4
=> the ratio of volume of the cone to the pyramid is:
= 
= (1/3*h*π
) / ( 1/3*h*4
)
= π/4
S we can conclude that the volume of the cone equals π/4 the volume of the pyramid
Hope it will find you well.
Hey can you please write down the Multiple question choices?
Answer:
70
Step-by-step explanation:
In parallelogram ABCD, diagonals AC and BD intersect at point E
E is the midpoint of BD
So BE = DE
Given: BE =2x^2-3x, and DE=x^2+10
BE = DE
(solve for x)
Subtract x^2 and 10 on both sides


Factor x^2-3x-10
(x-5)(x+2) = 0
x-5 =0 so x=5
x+2=0 so x=-2
Length x cannot be negative so we ignore x=-2
Lets plug in 5 for x and find out BE and DE
BE =
DE =
BD = BE + DE= 35+35 = 70
So BD = 70
It’s on like the side if I was home I would show my hw has the same answer/problem simple
