Answer:
He will earn $6 in interest in 9 months.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
Initial deposit of $400.
This means that 
2% annual interest
This means that 
How much interest will he earn in 9 months?
An year has 12 months, this means that 
This is E. So
He will earn $6 in interest in 9 months.
You can build a cylinder in two ways: either you draw a circle on a plane, and "raise" it perpendicularly to the plane itself, or you start with a rectangle, and rotate it around one of its sides.
For these reasons, if you cut the cylinder with a plane parallel to the base you have a circular cross section, while if you cut the cylinder with a plane perpendicular to the base you have a rectangular cross section.
Answer:
Here I have attached an image of the graph:
The answer is: " 3,723,875 cm³ " .

Note the exact conversion:
_________________________________
1m = 100 cm .
_________________________________
Convert: 1.55 m to "cm" ;
___________________________________________
1.55 m * ( 100 cm / m) = (1.55 * 100) cm = 155 cm .
___________________________________________
Now, to find the volume, in units of: " cm³ " ;
___________________________________________
(155 cm)³ = 155 cm * 155 cm * 155 cm ;
= (155 * 155 * 155) cm³ ;
= 3,723,875 cm³ .

A + [a + b - a - (2a- b)]
= a + (b - 2a + b)
= -a + 2b
