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.

Answer:
∠4 = 50°
Step-by-step explanation:
∠1 + ∠5 = 100°, but ∠1 = ∠5 ( corresponding angles ), hence
∠1 = ∠5 = 50°
∠4 = ∠1 = 50° ( vertical angles )
Expanding the right side:-
5x - 4 = 5x - 15 + 11
5x - 4 = 5x - 4
left side = right side so there are infinitely many solutions
