• Yes, I agree with Jada's strategy.

Find the area of the sector.

Which of these pizza slices gives the best value (the most pizza per dollar spent)?

• A: a slice with a radius of 12 inches, central angle of 30^\(\circ\), and a cost of $3 per slice

• B: a slice with a radius of 8 inches, central angle of 45^\(\circ\), and a cost of $2 per slice

The circle in the image has been divided into congruent sectors. What is the measure of the central angle of the shaded region in radians?

The image shows a circle with radius 5 units. Draw a 180 degree central angle (a diameter) in the circle. What is the length of the arc defined by this angle? Use the arc length and the radius to calculate the radian measure of 180 degrees.

Calculate the radian measure of a 360 degree angle. Explain or show your reasoning.

Complete the table. Each row represents a circle with a defined sector.

• A: radius 6 units, central angle 180 degrees

• B: radius 18 units, central angle 60 degrees

• C: radius 12 units, central angle 90 degrees

• D: radius 3 units, central angle 120 degrees

• E: radius 4 units, central angle 270 degrees
