It is shown that by looking at the formula for the volume of a cylinder (we assume that the trash can is cylindrical):
V = pi*r^2*h
We can conclude that the volume of the trash can is directly proportional to its radius and height. To wrap up, the volume would increase as the radius of the trash can's base, and its height would be increased as well.
4/9 + 1/5 (common denominator is 45)
20/45 + 9/45 = 29/45
It is 2.74 and if you have to round it ,it is 3.
