Answer:
V = 19.625h
Step-by-step explanation:
Volume of a cylinder V = πr²h
r is the radius
h is the height
Given
r = base/2
r= 5/2
r= 2.5
Substitute into the formula
V = π(2.5)²h
V = 3.14*6.25h
V = 19.625h
hence the required expression is V = 19.625h
An equation of the form y=ax+b, where y and x are variables, and a and b are constants, is called a linear equation.
The reason it is called linear is because the graph of the equation is a line.
The line passes through the origin only if b=0, as in our problem.
Any line (except vertical lines) represents a proportional relationship in that the change in y is proportional with the change in x. It is not a condition that the line passes through the origin.
In our specific case, y=(1/5)x, means that the change in y is always 1/5 of the change in x. That is, if x changes by 5 units, y changes by 1. If x changes by 10 units, y changes by 2, and so on.
So, the constant of proportionality is 1:5, or 0.2.

Answer:
874×1 = 874
874×10 = 8,740
874×100 = 87,400
874×1,000 = 874,000
