WebThe area of the square is straightforward: 30 * 30 = 900 square feet Because each side is 30 feet long, AB + BC + CD = 30. We can substitute BC for AB and CD since all three lengths are the same: BC + BC + BC = 30 3BC = 30 BC = 10 Therefore the diameter of the semicircle is 10 feet, so the radius is 5 feet. WebArea of sector is used to measure the central angle (θ) in degrees. As, the area of a circle=r 2 and the angle of a full circle = 360° Thus, the formula of the area of a sector of a circle is: Area of Sector Area of Circle = C e n t r a l A n g l e 360 ° A r e a o f S e c t o r π r 2 = 0 360 ° Area of Sector = 0 360 ° ∗ π r 2
