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 using the formula: multiply the angle in radians by 180/π. The tutorial also discusses the challenges of calculations involving Pi, emphasizing the need for approximation when exact values are not feasible. The video concludes by highlighting the necessity of approximating results when working with Pi.

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

• To ensure clarity in calculations

• To make the angle look more complex

• To confuse the students

• To avoid using radians

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

• Multiply by 90 degrees over π

• Multiply by 180 degrees over π

• Multiply by 360 degrees over π

• Multiply by 270 degrees over π

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 remain unchanged

• They add up

What is the approximate degree value of 360/π?

• 120.45 degrees

• 114.60 degrees

• 130.75 degrees

• 110.50 degrees

Why might you need to approximate when converting radians to degrees?

• Because π is an irrational number

• Because degrees are always approximations

• Because radians are more accurate

• Because calculators cannot handle π
