i think secondary source
Historians and researchers primarily base their research on primary sources such as original documents, artifacts, and data that provide firsthand accounts or direct evidence of past events. They also rely on secondary sources including scholarly books, articles, and analyses that interpret and discuss primary sources to develop a deeper understanding of historical events. Comparing and contrasting various sources helps to ensure accuracy and reliability in their research.

The circumference of a regular cylinder is the circumference of its circular face. C = pi * D (diameter of the cylinder) C = pi * 2r (or C = 2(pi)r)
Export base theory is an economic concept that highlights the importance of a region's export sector in driving economic growth and development. The theory suggests that focusing on exporting goods and services can lead to increased economic activity, job creation, and overall prosperity within a region. By expanding the export base, a region can attract investment, increase productivity, and improve its competitive position in the global market.
Having a broad base of knowledge helps individuals to understand complex issues from various perspectives, make connections between different subjects, and think critically. It also enables them to adapt to different situations, communicate effectively with people from diverse backgrounds, and continue learning and growing throughout their lives. A broad base of knowledge can also lead to more creativity and innovation by drawing on different fields for inspiration.
The formula for the volume of a cylinder is V = πr^2h, where r is the radius of the base and h is the height. Plugging in the values given (V = 6908, r = 10), we can solve for h to find that the height of the cylinder is 22 units.
A baseline in chain surveying serves as a reference line from which other measurements are taken. It helps ensure accuracy and consistency in the surveying process by providing a known starting point for establishing the position of other survey points. The baseline also acts as a control measure to check for errors and adjust measurements if needed.

Historians usually ask questions that begin with who, what, when, why and how. they tend to base their questions around one major question.
