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 sector of a circle is a partition of that circle. A sector extends from the center, or origin, of the circle to its circumference and encompasses the area of any given angle that also originates from the center of the circle. A sector is best thought of as a piece of pie, and ...
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.
To find the area of a circle, you take pi times the radius squared, or A = pi r^2. Using this formula, you can find the area of a circle if you know the radius -- or the diameter -- by plugging in your values and solving for A. Pi is approximated as 3.
