If you know the length of the arc (which is a portion of the circumference), you can find what. Area of a sector is the amount of space enclosed within the boundary of a sector. The formula for the area of a sector is (angle / 360) x π x radius2. When finding the area of a sector, you are really just calculating the area of the whole circle, and then multiplying by the remember the formula for finding the circumference (perimeter) of a circle is 2r. For a circle, that entire area is represented by a rotation of 360 degrees. Area of sector and length of an arc. If the length of arc(l) are given, we have to use the second formula. This is the currently selected item. Learn how to find the area of a rectangle & how to calculate trapezoid area to further strengthen your concepts related to area & surface. The area of a segment is the area of a sector minus the triangular piece (shown in light blue here). (the area bounded by a chord and an arc). Area of a sector calculator uses sector area formula to give accurate results. Explains the formulas for finding areas of sectors of circles and the lengths of their arcs, in each of degrees and radians.

There must be a typo in this question, why does the formula for finding the surface area of arectangular prism is helpful? (the area bounded by a chord and an arc). A = 1⁄360θπr2 example problems. To recall, a sector is a portion of a circle enclosed between its two radii and the arc adjoining them. A = area of a sector π = 3.141592654 r = radius of the circle θ = central angle in degrees.
