Pi is a number defined as the ratio of the circumference to the diameter of a circle. many simplify it as 3.14, however, pi is an irrational number, so unless the number is specified in the directions or by the instructor, keep pi as its symbol similar to using an "x" in algebra

Volume of a cylinder = pi*radius2*height
pi x r2 x height
Some of the many applications that pi is used in geometry are as follows:- Finding the area of a circle Finding the circumference of a circle Finding the volume of a sphere Finding the surface area of a sphere Finding the surface area and volume of a cylinder Finding the volume of a cone
divide the volume by 2*pi*r where r is the radius of the base
Presumably the question is about finding the volume of a cylinder? Volume of a cylinder = pi*radius2*height Volume = 2309.0706 cubic units
