Perimeter of sector area
WebMar 11, 2024 · This gives you the area of the sector. For example, 0.28 x 78.5 = 21.89. Since you are finding the area, the answer will be in square … WebThen, the area of a sector of circle formula is calculated using the unitary method. When the angle at the centre is 360°, area of the sector, i.e., the complete circle = πr². When the angle at the center is 1°, area of the sector =. π. r 2 360 0. Thus, when the angle is θ, area of sector, OPAQ =.
