Find the Arc Length and the Area of a Sector of a Circle Step 1:Note the radius of the circle and whether the central angle is in radians or degrees. Step 2:Use the appropriate formula to find either the arc length or area of a sector. ...
The formula for the area of a sector is: A = r² ×θ / 2 How to find the length of an arc and sector area: an example Decide on the radius of your circle. For example, it can be equal to 15 cm. (You can also input the diameter into the arc length calculator instead.) Wh...
To find the Arc Length and Sector Area of a circle, you need the formulas and in this article, we review and explain these formulas.
Length of an Arc = θ× (π/180) × r, where θ is in degree. How to Find Arc Length Without the Radius? The arc length of a circle can be calculated without the radius using: Central angle and the sector area: Thesector areaformula is, (θ/360º) ×πr2, if θ is in deg...
Circle, sector, segment, string and arc length, area online formula calculator Lines AO and OB are called radii. Lines AC, BC and AB are called strings. The angle ABC is an inscribed corner. The angle AOB is the central angle. The curved line is called the arc AB. The line segment ...
Find Arc Length using Sector Area and Central Angle You can also find the length of the arc if the sector area and central angle are known using the formula: arc length (s) =2θ × A The arc lengthsis equal to the square root of 2 times the central angleθin radians, times the se...
