: 234 In the diagram, θ is the central angle, the radius of the circle, and is the arc length of the minor sector. Homework. The pointed leg of the compass is placed on the paper and the movable leg is revolved as shown. Name the parts of a circle. The shape of a sector of a circle can be compared with a slice of pizza or a pie. The traced figure gives us a circle.In the below figure, various points are marked lying either outside or inside the circle or on the circle. where L represents the arc length, r represents the radius of the circle and θ represents the angle in radians made by the arc at the centre of the circle.If the value of angle is given in degrees, then we can also use the following formula bywhere C represents the chord length, R represents the radius of the circle, and θ represents the angular width of the sector in radians. 2, points P, S and R lie on the circumference of a circle and on joining these points with the centre, i.e. 0. A sector is said to be a part of a circle made of the arc of the circle along with its two radii.

We have moved all content for this concept to for better organization. In other words, a A circle can have different parts and based on the position and shape, these can be named as follows:As we have already discussed the centre and radius of a circle. Sector . 0. 10 cm.Figure 1 given above, represents a circle with radius ‘r’ and centre ‘O’. Played 9 times. In layman terms, the round shape is often referred to as a circle. Many objects that we come across in our daily life are ‘round’ in shape such as a coin, bangles, bottle caps, the Earth, wheels etc. Given a line and a circle, it could either be touching the circle or non-touching as shown below:In the first fig. Solo Practice. Based on this any point can be defined as:A point X is said to lie on the circumference of a circle with centre ‘O’ if OX = rIn fig. the line AB intersects the circle at two distinct points P and Q. A closed plane figure, which is formed by the set of all those points which are equidistant from a fixed point in the same plane, is known as a circle. Circle. Mathematics. This can be understood with the help of an example. Because 120° takes up a third of the degrees in a circle, sector IDK occupies a third of the circle’s area.

In geometry, a circle is a closed curve formed by a set of points on a plane that are the same distance from its center O. A circle can have any number of chords. AOB is a sector of a circle with O as centre. The following figures show the different parts of a circle: tangent, chord, radius, diameter, minor arc, major arc, minor segment, major segment, minor sector, major sector. Please update your bookmarks accordingly. The figure given below illustrates the various terms related to parts of a circle as explained above. Here’s the formal solution: Find the area of circle segment IK. Radius: The radius of the circle of which the sector is a part : Central Angle: The angle subtended by the sector to the center of the circle. AOB is a sector of a circle with O as centre.The figure given below illustrates the various terms related to parts of a circle as explained above.

To find the segment area, you need the area of triangle IDK so you can subtract it from the area of sector IDK. Scroll down the page for more examples and explanations. The line AB here is called In the second figure, the line AB touches the circle exactly at one point, P. A line touching the circle at one single point is known as the In the last figure, the line does not touch the circle anywhere, therefore, it is known as a non- intersecting line.A line segment joining two different points on the circumference of a circle is called a chord of the circle. A circular sector or circle sector (symbol: ⌔), is the portion of a disk enclosed by two radii and an arc, where the smaller area is known as the minor sector and the larger being the major sector. Live Game Live. A sector of a circle is the part bounded by two radii and an arc of a circle. Edit.
