What is the volume of a right circular cylinder with a radius of 4 m and a height of 4 m?

The volume of a cylinder by definition is given by:
 V = ((pi) * (r ^ 2)) * (h)
 Where,
 r: radio
 h: height.
 We have then:
 V = ((pi) * ((4) ^ 2)) * (4)
 V = 64 * pi m^3
 
 The volume of a right circular cylinder is
 V = 64 * pi m^3

It's like discovering the answer to a puzzle. the purpose in solving an equation is to find the value or values of the variable that makes it a true statement. any value of the variable that makes the equation true is called a solution to the equation.
