In 1990, Sapir's Soup Company used a cylindrical can with radius 3 centimeters, filled to a height of 4 centimeters. If in 1995, Sapir's Soup Company changed the height of the can by 5 centimeters and filled it with the same amount of soup, which of the following could be the radius of the can in 1995?

A. 1

B. 2

C. 4

D. 8

E. 9

Given volume of cylindrical can in 1990(r=3, h=4)=volume of cylindrical can in 1995(r=to be determined, h=4+5=9)

Or, \(\pi*3^2*4=\pi*r^2*9\)

Or, \(r^2=\frac{9*4}{9}\)

Or, \(r=\sqrt{4}=2\)

Ans. (B)
