It is asking you to move the right formula with its match.
Formula for a cylinder: π*R^2*H
So the first option goes to the first shape.
Example:
Radius=5
Length=10
π≈3.14
3.14*5²*10
=725 cm³ for the answer.
Formula for a square: l*w*h
So the 4th option goes with the 2nd shape.
Example: l=5 w=5 h=5
(Length * Width * Hieght)
5*5*5=125 for the answer.
Formula for a cone is: 1/3π*r^2*h
So the second option goes to the 3rd shape.
Example: r=3 h=11
π≈3.14
33 is your answer.
Formula for the pyramid would be: 1/3*b*h
So the 3rd option would go to the 4th shape.
Example:
b=2 h=10
Rounded: 6.6

If we say that side "a" is the shortest (adjacent), side "b" is the second shortest (opposite), and side "c" is the longest (hypotenuse): then angle A would be 30°, angle B would be 60°, and angle C would be 90°
tan B = b/a
or
a tan B = b
they have 4 as the smallest value in all four options, so we know that a=4
4 tan 60° = b
tan 60° = √3
so, 4 tan 60° = 4√3
b=4√3
that leaves two options left, so now we find "c":
c^2 = (a^2) + (b^2)
OR
so a=4, b=4√3, and c=8
