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.
Answer:
V = 108,000,000pi or V = 339292007mm
Step-by-step explanation:
V = pi × r^2 × h
To find radius with circumference:
Radius = Circumference / 2pi
So, 1884/2pi = 299.847913 = 300
V = pi × 300^2 × 1200
V = pi × 90000 × 1200
V = pi × 108000000
V = 108,000,000pi or V = 339292007
To solve this problem, simply use one variable to represent the number of students in each of the 2 classes.
1st class - X = no of students
2nd class - X + 6 no of students
Both classes : X + X + 6 = 50
2X + 6 = 50
2X = 44
X = 22.
1st class - X = 22 students
2nd class - X + 6 = 22 + 6 = 28 students.
There are 28 students in the larger class.

20= 2(x-4)
20/2= 2(x-4)/2
10= x-4
+4 . +4
14=x
