Acylinder has a volume of 136 cubic centimeters. what is the volume of a cone with the same height and the same diameter

Volume of a cylinder = pi r^2 h If the cone has exactly the same measurements then its formula is going to be
V_cone = 1/3 pi r^2 h. If that's the case the only difference is that the Cone's volume is 1/3 that of the cylinder
V_cone = 1/3 V_cylinder
V_cone = 1/3 136 cubic cm.
V_cone = 45.33 cubic cm.
