Question

Volume of a cylinder: The volume of a right circular cylinder of height h and radius r is V=(Pi)r^2h. If the height is twice the radius, express the volume V as a function of r 

Answer 1

Hello Lauren

 

Height is twice the radius, which translates to h = 2r. Substitute this relationship into the Volume equation, you get

 

V = πr²(2r)

 

V = 2πr³
