relationship in volume between cylinder and cone

• cylinder formula

  v - area base x height

  A - pi r 2
• if the cone has the same base and height as the cylinder, it is 1/3 of the volume of the cylinder
• cone

  v - 1/3 pi r 2 h
• radius: a straight line from the centre to the circumference of a circle or sphere.
• diameter: a straight line passing from side to side through the centre of a body or figure, especially a circle or sphere.
