 Hello and welcome to the session I am Deepika here. Let's discuss the question which says find the area of a sector of a circle with radius 6 centimeter if angle of the sector is 60 degree. Let us first understand how to find the area of sector of a circle. Now we know that the portion of the circular region enclosed by two radii and the corresponding arc is called a sector of the circle. Let in this figure pb be a sector of a circle with center o and radius r. Let degree measure of angle aobb theta. Now we know that the area of a circle is pi r square. In a way we consider this circular region to be a sector forming an angle of 360 degree. So when degree measure of the angle at the center is 360 then area of the sector is pi r square. So when degree measure of the angle at the center is 1 then area of the sector is pi r square upon 360. Therefore when the degree measure of the angle at the center is theta then area of the sector is pi r square upon 360 into theta. Hence we have opened the formula for area of the sector of angle theta is equal to theta upon 360 into pi r square. Now we will use this formula to solve the above question. So this is a key idea behind our question. We will take the help of this key idea to solve the above question. So let's start the solution. Now given sector is a pb. Here radius of the circle is given to us 6 centimeter. Angle of the sector is 60 degree. That is theta is equal to 60 degree. Now we know that the area of the sector of angle theta is equal to theta upon 360 into pi r square. Now here r is 6 centimeter and theta is equal to 60 degree. So area of the given sector is equal to p upon 360 into 22 by 7 use pi is equal to 22 by 7 into radius is 6 centimeter 6 into 6 centimeter square. So on cancellation we have area of the given sector is equal to 22 into 6 upon 7 centimeter square or this is equal to 132 upon 7 centimeter square. Hence the area of a sector of a circle with radius 6 centimeter and if angle of the sector is 60 degree is 132 upon 7 centimeter square. This is our answer. I hope the solution is clear to you. Bye and take care.
