Converting to radians as an approximate value

The video tutorial explains the conversion of degrees to radians using π, detailing the calculation process and rounding to three decimal places. It covers the concept of radians, their representation on a graph, and the importance of leaving answers as multiples of π. The tutorial also clarifies the concept of negative angles and uses a noodle analogy to help visualize radians.

What is the formula used to convert degrees to radians?

• Multiply by 180/π

• Multiply by π/180

• Divide by π

• Add π to the degree

When converting -216.35 degrees to radians, what is the result rounded to three decimal places?

• -3.778

• -3.777

• -3.775

• -3.776

How many radians are there in a full circle?

• 2π radians

• π radians

• 360 radians

• 180 radians

What does a negative angle indicate in terms of direction?

• A positive measurement

• A clockwise direction

• An anti-clockwise direction

• A larger angle

Why might you leave an answer in terms of π?

• To simplify calculations

• To find an approximate value

• To express the exact value

• To avoid using a calculator
