Answer:
Step-by-step explanation:
(1). A = π r²
A = 4 π
Area of shaded region is =
or
(2). C = 4 π
In this case, the length of the bigger arc and the area of shaded region happen to be the same.
The length of the arc ADB is or

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
