The volume of a right circular cylinder can be approximated as follows: Volume = ?r2h; where r is the radius of the cylinder and h is the height of the cylinder; ? 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.

The volume of a right cylinder is the area of the base times the height of the cylinder.

If ? = 3, r = 2m, h = 9m

The equation is ?r2h, then:

3 * [tex]2^{2}[/tex] m * 9m = 108 m3


The volume of the required right circular cylinder is 108 [tex]m^{3}[/tex]

What is a right circular cylinder?

"It is a cylinder with circular bases and an axis connecting the two bases' centers that is perpendicular to the bases' planes."

How to calculate the volume of it?

According to the question:

  • Volume = [tex]xr^2h[/tex];
  • Where x = 3.

Given:

  • the radius is 2 meters
  • the height of 9 meters

Therefore the volume of the right circular cylinder is

  • = [tex]3*(2^2)*9 = 108 m^3[/tex]
