Accepted Solution

A:

Answer: noStep-by-step explanation:If we consider the volume of each orange ( we have considered the orange as a perfect sphere)we have the volume=(4/3) * π R^3 where is the orange radiusfor 3 inch diameter de volume is =1.33*3.1415*3.37 inch^3for 4 inch diameter de volume is =1.33*3.1415*8 inch^3Taking into account a dozen of oranges we have to multiplier by 12 both orange volume are:V dozen 3-inch= 40.44 inch^3 (paying 25 cent)V dozen 4-inch= 96.00 inch^3 (paying 50 cent)If she want to buy more that one dozen is economical better choose the 4 inch oranges
