Question 1

What is the formula for calculating arc length?

Arc Length = (Angle of Sector / 360) * (2 * π * r)
Arc Length = π * r
Arc Length = (360 / Angle of Sector) * (2 * π * r)

💡 Hint: Remember, the angle divides the circle into parts.

Question 2

True or False: The area of any sector of a circle always adds up to 360 degrees.

True
False

💡 Hint: Think about the units of measurement used.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A sector has a radius of 12 cm and an arc length of 8π cm. Determine the central angle of the sector.

💡 Hint: Rearranging the formula will help you isolate the angle.

Challenge 2 Hard

Given the area of a sector is 20π cm² and the radius is 10 cm, find the measure of the central angle.

💡 Hint: Multiply both sides by 360 and then isolate the variable.
