Write a function rule for the volume of the cylinder shown at the right with a height 3 in more than 4 times the radius of the cylinder's base. what is the volume of the cylinder when it has a radius of 2 in?

Volume of a cylinder = π r² h

radius = 2 inches
height = 3 inches more than 4 times the radius. 4(2) + 3 = 8 + 3 = 11 inches

Volume of a cylinder = 3.14 * (2in)² * 11 inches
Volume of a cylinder = 3.14 * 4in² * 11 inches
Volume of a cylinder = 138.16 in³
