Arc Length and Circumference Quiz

What does the Greek letter lambda represent in the context of arc length?

• Radius

• Arc length

• Central angle measure

• Circumference

Which variable is used to denote the circumference in the arc length formula?

• M

• R

• C

• Lambda

What is the formula to calculate arc length in terms of circumference and central angle?

• Arc length = 2 * pi * R

• Arc length / Circumference = M / 360

• Arc length = Circumference * M

• Arc length = M * 360
