The volume of a right circular cylinder can be approximated as follows:Volume = πr2h;where r is the radius of the cylinder and h is the height of the cylinder;π is a constant that is roughly equal to 3.Using the simple approximation above, calculate the volume of a right circular cylinder with a radius of 2 meters and a height of 9 meters.

Answer:

Volume of the right circular cylinder is [tex]113.04 m^{3} \\[/tex]

Explanation:

Given -

Radius of the right circular cylinder [tex]= 2\\[/tex] meters

Height of the right circular cylinder [tex]= 9\\[/tex] meters

The volume of the right circular cylinder is given by the following formula

[tex]\pi r^{2} h\\[/tex] ..............Eq (A)

Where,

[tex]\pi = 3.14\\[/tex] , a constant

[tex]r = \\[/tex] radius of the cylinder in meters

[tex]h = \\[/tex] height of the cylinder in meters

Substituting the given values in above equation A, we get -

[tex]\pi r^{2} h\\= (3.14) ( 2^{2}) (9)\\ = 113.04 m^{3} \\[/tex]

Thus, Volume of the right circular cylinder is [tex]113.04 m^{3} \\[/tex]
