How to convert an angle in degrees to radians - Free Math Help - Online Tutor

The video tutorial explains how to convert angles from degrees to radians. It starts with an example of converting 30 degrees to radians by multiplying by π/180. The process is simplified to π/6, and the application of this conversion in the unit circle is discussed.

What is the first step in converting an angle from degrees to radians?

• Multiply the degree value by π/180

• Add 180 to the degree value

• Divide the degree value by π

• Subtract 30 from the degree value

If you have an angle of 30 degrees, what is the equivalent in radians?

• π/2

• π/6

• π/4

• π/3

What is the simplified form of 30/180 in the context of converting degrees to radians?

• 1/3

• 1/6

• 1/2

• 1/4

How do you express 1/6 in terms of π when converting degrees to radians?

• π/3

• π/6

• π/2

• π/4

What is the purpose of using the unit circle in the context of radians?

• To calculate the circumference

• To convert radians back to degrees

• To visualize fractions of π

• To measure angles in degrees
