This tutorial will first show how to identify what fraction of the circle is occupied by 2020-07-08 Visit www.doucehouse.com for more videos like this.

Area of Sector. The area of a sector of a circle is ½ r² ∅, where r is the radius and ∅ the angle in radians subtended by the arc at the centre of the circle. So in the below diagram, the shaded area is equal to ½ r² ∅ . See the video below for more information on how to convert radians and degrees

Note the number of square units it takes to fill it and the calculation. If you know the radius of the circle and the height of the segment, you can find the segment area from the formula below. The result will vary from zero when the height is zero, to the full area of the circle when the height is equal to the diameter. A sector of a circles is the region bounded by two radii of the circle and their intercepted arc. The surface area and volume of a cylinder and cone with circular bases contain the formula for area of circle. The lateral surface of a cone consists of all segments that connect the vertex with points on the base. The formula for the area of a circle (more properly called the area enclosed by a circle or the area of a disk) is based on a similar method.

The calculator will show you the chart of the sector based on your input as well.

Now, we know that the diameter of the pizza is four inches less than 16 inches. That is, it is 12 inches. Be careful! The area of the circle is given in terms of radius , 

So the area of the sector is this fraction multiplied by the total area of the circle. or (θ/2π) x (πR 2) = θR 2 /2 with θ in radians. Se hela listan på calculatored.com The area, A of the circle with radius r is given by \(A\) = \(π~r^2\) Definition 3: The portion of the circle enclosed by two radii and the corresponding arc is known as the sector of a circle. Basically, a sector is the portion of a circle. It would hence be right to say that a semi-circle or a quarter-circle is a sector of the given circle. Example 1: A sector is cut from a circle of radius 21 cm. The angle of the sector is 150º.
