Area of a Sector - Formula | Area of Sector of a Circle - Cuemath
When the angle subtended at the center is given in degrees, the area of a sector can be calculated using the following formula, area of a sector of circle = (θ/360º) × πr 2, where, θ is the angle subtended at the center, given in degrees, and r is the radius of the circle.
Sector Area Calculator
2024年7月30日 · The formula for sector area is simple – multiply the central angle by the radius squared, and divide by 2: Sector Area = r² × α / 2; But where does it come from? You can find it by using proportions. All you need to remember is the circle area formula (and we bet you do!): The area of a circle is calculated as A = πr². This is a great ...
