Learn how to convert an angle in radians whole number to degrees

The video tutorial explains the importance of specifying angle units, particularly when dealing with degrees and radians. It provides a step-by-step guide on converting angles from radians to degrees by multiplying the angle by 180/π. The tutorial also discusses the necessity of approximating results when π is involved, especially when the angle is not expressed in terms of π. The video concludes with a reminder about the common practice of approximation in such mathematical conversions.

Why is it important to specify the unit of an angle?

• To avoid using radians

• To confuse the students

• To make the angle look more complex

• To ensure clarity in calculations

What is the formula to convert an angle from radians to degrees?

• Multiply by 360 degrees over π

• Multiply by 180 degrees over π

• Multiply by 90 degrees over π

• Multiply by π over 180 degrees

What happens to the π terms when converting an angle in terms of π from radians to degrees?

• They multiply together

• They cancel each other out

• They add up

• They remain unchanged

If an angle is not in terms of π, what must be done during conversion?

• Use a calculator to approximate

• Convert it to radians first

• Multiply by π

• Divide by 180

What is the approximate degree value of 360/π?

• 57.30 degrees

• 360 degrees

• 180 degrees

• 114.60 degrees
