Question
The total surface area of a cylinder of height 6.5 cm is 220 sq. cm. Find its volume.
Hint:
The volume of a cylindrical container with base radius r and height h, is 
cubic units. And the TSA of the cylinder is 
.
The correct answer is: Its volume is 250.25 cm3
Explanations:
Step 1 of 2:
Given,
Solving the above quadratic equation, we get r = 3.5, discarding the negative value.
Step 2 of 2:
We have r = 3.5 cm and h = 6.5 cm
The volume of the cylinder is
cm3
Final Answer:
Its volume is 250.25 cm3

During mineral formation, the same chemical compound can beco me different minerals depending on the temperature and pressure at the time of formation. A phase diagram is a graph that shows the conditions that are needed to form each mineral. The graph above is a portion of the phase diagram for aluminosilicates, with the temperature t , in degrees Celsius 
, on the horizontal axis, and the pressure p , in gigapascals (GPa), on the vertical axis.
An equation of the boundary line between the andalusite and sillimanite regions is approximated by the equation above. What is the meaning of the T-intercept of this line?
Note;
A phase diagram represents the different physical states of some substance under different conditions, such as termperature and pressure, graphically. It may seem like a complicated graph but we just needed to focus on the equation of one given line.

The circumference of Earth is estimated to be 40,030 kilometers at the equator. Which of the following best approximates the diameter, in miles, of Earth's equator? (1 kilometer 
miles)
Note:
There are many other units of length which are often used. For example: inch, foot, yard, centimetre, parsec, lightyear, nanometre, etc. They measure anything between atoms to a galaxy.
Some relations between them are given by
1 kilometer = 39370.0787 inches = 3280.84 feet = 100000 centimetre
1 mile = 63357 inches = 5279.75 feet = 160926.94 centimetre
