Question

Match the formula to the correct figure.

Answer 1

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
$\frac{1}{3} *3 ^{2} *11=33$
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
$\frac{1}{3} *2*10=6.666667$
Rounded: 6.6

Answer 2

These are the formula's for each of the 3 dimensional shapes. They're asking you to match the formula to the correct shape. 

Here, you'll need just a bit of memorizing. 

Orange figure : Cylinder
V=πr²h

Yellow figure: Square
length * width * height
V = l×w×h

Blue figure: Cone
V = 1/3πr²h

Red figure: Pyramid
 V = 1/3 b * h

Pi = 3.14
h = height
b = base
r = radius (half of diameter)
v = volume
