 Hello and welcome to the session. In this session we discuss the following question which says draw a circle with center O and radius 3 cm, draw sector having the angle 68 degrees. First of all let's recall what is the sector of a circle. The area bounded by an arc and the two radii joining the end points with the center is called a sector. This is the key idea that we use for this question. Now let's see the solution. For we will draw a circle with center O and radius 3 cm. So this is a circle with center O. O A is the radius of the circle where O A is equal to 3 cm. Next we need to draw a sector having the angle 68 degrees. To draw the sector using the protractor we will keep the protractor with its center point on the center of the circle and the base line of the protractor along the radius of the circle and we mark the point indicating the angle measuring 68 degrees. So we are drawn this angle AOB measuring 68 degrees. As we know that the sector of a circle is the area bounded by an arc and the two radii joining the end points of the arc with the center. Consider any point C on the arc AB of the circle. Now this sector O A CB is the minor sector and take any point D on the major arc of the circle. So this ADB is the major arc of the circle and hence O A DB is the major sector of the circle. Major sector is formed by the major arc of the circle and the minor sector is formed by the minor arc of the circle. So we have drawn a circle with radius 3 cm and having a sector of angle equal to 68 degrees. This completes the session. Hope you have understood the solution of this question.
