Area Of A Sector Calculator To calculate the area of the sector of a circle, you can use two methods. if you know the radius and central angle: convert the central angle into radians: α [rad] = α [deg] · π 180°. multiply the radius squared by the angle in radians. divide the result by 2. if you know the area of the circle and central angle:. In order to find the total space enclosed by the sector, we use the area of a sector formula. the area of a sector can be calculated using the following formulas, area of a sector of circle = (θ 360º) × πr 2, where, θ is the sector angle subtended by the arc at the center, in degrees, and 'r' is the radius of the circle.
Area Of A Sector And Segment Solutions Examples Worksheets Videos Sector area using degrees. if you know the central angle in degrees, then the formula to find the area of a sector is a little different: sector area = θ 360 × πr². the area is equal to the central angle θ in degrees divided by 360, times pi times the radius squared. The formula for the area of a sector is (angle 360) x π x radius2. the figure below illustrates the measurement: as you can easily see, it is quite similar to that of a circle, but modified to account for the fact that a sector is just a part of a circle. measuring the diameter is easier in many practical situations, so another convenient. Solution: step 1: find the area of the entire circle using the area formula a = πr 2. step 2: find the fraction of the circle by putting the angle measurement of the sector over 360°, the total number of degrees in a circle. step 3: multiply the fraction by the area of the circle. leave your answer in terms of π. 1. set up the formula . in the formula, r = the length of the radius, and θ "theta" = the degrees in the central angle of the sector. [1] remember, the area of a circle is. π r 2 {\displaystyle \pi r^ {2}} when finding the area of a sector, you are really just calculating the area of the whole circle, and then multiplying by the fraction of.

Area of sector = θ2 × r 2 (when θ is in radians) area of sector = θ × π 360 × r 2 (when θ is in degrees) area of segment. the area of a segment is the area of a sector minus the triangular piece (shown in light blue here). there is a lengthy reason, but the result is a slight modification of the sector formula:. Example 1: find the area of the sector in terms of π if the circle has a radius of 8 units and a central angle of 45 degrees. solution: using the formula for sector area, we write. area = θ 360 ∘ × π r 2. here, r = 8 units, θ = 45 ∘. area = 45 ∘ 360 ∘ × π × 8 2. area = (1 8) × π × 64. area = 8 π square units.
