Explain the Error. A student said the volume of a cylinder with a 3- inch diameter is two times the volume of a cylinder with the same height and a 1.5 inch radius. What is the error?
Because the formula for the volume of a cylinder is [tex]\pi r^2 h[/tex], when you multiply the radius by 2, the volume increases by [tex]2^2=4[/tex] times. Hope this helps!
