 Hello, and welcome to the session. In this session, we will discuss a question which says that an arc supplies an angle of 90 degrees at the center of the circle of radius 14 centimeters line the area of minus sector, thus formed in terms of pi. And the options are option A, 7 pi centimeter square, option B, 14 pi centimeter square, option Z, 49 pi centimeter square, option D, 98 pi centimeter square. Now before starting the solution of this question, we should know our result. And that is area of the sector of the angle theta is equal to theta by 360 into pi r square, where theta is the angle of the sector in degrees and r is the radius of the circle. Now this result, we welcome to the key idea solving out this question. And now, we will start with the solution. Here, the angle theta is given as 90 degrees and the radius is given as 14 centimeters. So given theta is equal to 90 degrees and r, this is the radius, is equal to 14 centimeters. Now by using the formula which is given in the key idea, so using the formula which is given in the key idea, area of the sector is equal to theta by 360 into pi r square. Now put in the values of theta and r here, it will be 90 by 360 into pi into 14 into 14 centimeters square. Further, this is equal to 0, where we cancel with 0. 9 into 4 is 36, 2 into 2 is 4, and 2 into 7 is 14. Here again, 2 into 7 is 14. So this is equal to 49 pi centimeter square. Therefore, area of the sector is equal to 49 pi centimeter square. So the answer of this question is option p, which is 49 pi centimeter square. So this is the solution of the given question and that's all for this session. Hope you have enjoyed the session.
