Section 7.1: Angles

What is the measure of a full circular rotation in degrees?

• 270 degrees

• 90 degrees

• 180 degrees

• 360 degrees

What is the radian measure equivalent to 180 degrees?

• π/4 radians

• π/2 radians

• 2π radians

• π radians

Which angle is a quadrantal angle?

• 30 degrees

• 90 degrees

• 45 degrees

• 60 degrees

How many radians are in a complete rotation?

• 2π radians

• π radians

• 4π radians

• π/2 radians

What is the linear speed formula?

• v = s + t

• v = t / s

• v = s * t

• v = s / t

What is the measure of an angle formed by a full rotation in radians?

• π radians

• 2π radians

• 3π/2 radians

• π/2 radians

What is the correct expression for converting degrees to radians?

• Radians = (Degrees * 180) / π

• Radians = (Degrees * π) / 180

• Radians = (Degrees / 180) * π

• Radians = (Degrees / π) * 180

Which of the following is a unit of angular speed?

• Meters per second

• Radians per second

• Seconds per radian

• Degrees per meter

What is the area of a sector formula when the angle is in radians?

• Area = (1/2) * θ * r^2

• Area = θ * r^2

• Area = (π/2) * θ * r^2

• Area = (2π) * θ * r^2

How do you find a coterminal angle for an angle greater than 360 degrees?

• Divide by 360 degrees

• Multiply by 360 degrees

• Add 360 degrees until within range

• Subtract 360 degrees until within range
