Given:
The figures cylinder, cube, cone, and pyramid.
To find:
The formula of volume for the given figures.
Solution:
Volume of a cylinder is:

Where r is the radius and h is the height.
Volume of a cube is:

Where a is side length of cube.
It is also written as:

Where l is length, w is width, h is height and
.
Volume of a cone is:

Where r is the radius and h is the height.
Volume of a pyramid is:

Where B is the base area and h is the height.
Therefore the table of formulae is shown below:

Answer:
≈ 70.4 cm
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius ) , thus
C = 2 × 3.142 × 11.2 ≈ 70.4 ( to 1 dec. place )
