Since the radius of this circle is 3 inches, the area of the green sector is 57π/8 square inches.
In Mathematics and Geometry, the area of a sector can be calculated by using the following formula:
Area of sector = π
× θ/360
Where:
- r represents the radius of a circle.
- θ represents the central angle.
Note: The measure of an intercepted arc is equal to the central angle of a circle.
By substituting the given parameters into the area of a sector formula, we have the following;
Area of sector = π
× θ/360
Area of sector = π ×
× 285/360
Area of sector = π × 9 × 57/72
Area of sector = π × 57/8
Area of sector = 57π/8 square inches.
