What is the sector area? A sector is a piece of a circle. The area of a sector is a portion of the area of the circle, and can be found with a formula.
What is the formula for Sector Area? Sector Area = X/360(pi times r (squared)
What is a chord? When you draw a line segment from one part of a circle to another that does not go through the center of the circle.
What is a segment of a circle? the area between a chord and the outside of a circle.
How do you find the area the segment of a circle? Sector Area - Triangle Area x/360(pi times r squared) - 1/2bh
