Flashcardizz: Area of a Sector

Area = (θ/360) × πr², where θ is the angle in degrees and r is the radius.

A sector is a portion of a circle enclosed by two radii and the arc between them.

Arc Length = (θ/360) × 2πr, where θ is the angle in degrees and r is the radius.

The area of a sector increases with the square of the radius.

Area = (90/360) × π(7)² = 38.48 cm².

The angle determines the proportion of the circle that the sector represents.

Area = (60/360) × π(5)² = 13.09 cm².

Common units include square centimeters (cm²), square meters (m²), and square inches (in²).

The area of a sector is a fraction of the area of the entire circle, based on the angle.

Area = (180/360) × π(10)² = 157.08 cm².
