The volume , v ,of a cone having radius , r ,and height , h , is given by the formula V= 1/3 pi r^ 2 h A. Use the equation and derive a formula to find the radius of a cone for a given volume and height.

B. Using the formula derived in part A, describe the relationship between the height of the cone and the radius for a constant volume.
