The amount of juice in a grapefruit is directly proportional to the cube of its diameter. Let j represent the amount of juice (in fluid ounces) in a grapefruit, let d represent the diameter (in inches) of the grapefruit, and let k be the constant of proportionality. Write an equation that relates j to d.
j =
A grapefruit with a 4-inch diameter contains 6 fluid ounces of juice. Use the equation that relates j to d and the known information to find k.
k =
