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? In this short article we'll: So let's start with the sector definition - what is a sector in geometry? sector noun [C] (ECONOMIC AREA) C1 one of the areas into which the economic activity of a country is divided: In the financial sector, banks and insurance companies have both lost a lot of money. Use sector area formula to estimate the size of a slice for your guests so that nobody will starve to death. Answer Save. The arc length of a sector is the portion of circumference that the sector takes up from the whole circle. The full angle is 2π in radians, or 360° in degrees, the latter of which is the more common. in D. 100 sq.in Of course, you'll get the same result when using sector area formula. Find the radius of the circle. The Bay Area employment base is remarkably diverse, with nearly 3.7 million individuals working for thousands of employers in nearly a dozen primary industrial sectors. AREA OF SECTORS SECTORS of a circle are formed by the two radii of a central angle and the arc between their endpoints on the circle. The Plan uses a watershed based planning approach. Area and Arc Length of a Sector Tutoring and Learning Centre, George Brown College 2014 www.georgebrown.ca/tlc For angles of 2π (full circle), the area is equal to πr²: So, what's the area for the sector of a circle: From the proportion we can easily find the final sector area formula: If you're wondering how big cake you should order for your awesome birthday party - bingo, that's it! The Life Sciences industry in Northern California is vigorously thriving, and San Francisco is a major catalyst of this development. The arc is the outer edge of the sector.
