Answer:
220,781.25 cubic cm
Step-by-step explanation:
Given ratio of the diameters = 15:11
Let the actual value of of diameters be 15x and 11x to maintain the ratio of 15:11
Given that smaller one has diameter of 55cm
thus 11x = 55cm
x = 55/11 cm = 5
Thus, diameter of larger ball = 15xcm= 15*5cm =75cm.
we know that radius is half of diameter
Radius = diameter/2
Thus radius of larger ball = 75/2 cm = 37.5 cm.
Volume of sphere is given by 
we know that ball has spherical shape
thus volume of larger ball is calculated as given below

Thus, volume of larger ball is 220,781.25 cubic cm
The correct answer is A, it has -1. While B's got 1.
Yes cause he can decrease the perimeter in any way and it would change the area and idk the other 2 in the front
