B.

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
`r^(2)`

• The formula to find the volume of the pyramid is:

V2 = 1/3*the height*the base area

<=> V = 1/3*h*4
`r^(2)`

=> the ratio of volume of the cone to the pyramid is:

=
`(V1)/(V2)`

= (1/3*h*π
`r^(2)` ) / ( 1/3*h*4
`r^(2)` )

= 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.
